  • Rare Earth Elements Deposits in New Mexico (Chapter3, Special Paper #9)

    Rare Earth Elements Deposits in New Mexico (Chapter3, Special Paper #9)

    Basic Information
    Author:

    McLemore, V.T.

    Description:

    in New Mexico, but they have not been important exploration targets in past years because demand has been met elsewhere. However, with the projected increase in demand and potential lack of available REE production from China, the New Mexico deposits are being re-examined for their potential. REE-Th-U veins are found in the Gallinas, Caballo, Capitan, and Cornudas Mountains and Laughlin Peak-Chico Hills. A small amount of bastnaesite, a REE mineral, was recovered during processing for fluorite from the Gallinas Mountains. Four types of deposits are found in the Gallinas Mountains: epithermal REE-F veins, Cu-REE-F veins, REE-F breccia pipes and iron skarn deposits; all are associated with Tertiary alkaline to alkalic-calcic igneous rocks. Resources amount to at least 537,000 short tons of 2.95% total REE (not NI-43-101 compliant; Schreiner, 1999). The abundant rare mineralogy in the Cornudas Mountains suggests that the area has potential for undiscovered deposits of REE, niobium, and zirconium. U.S. Borax sampled and drilled in the Chess Draw area (up to 0.06% total rare-earth oxides, 10-1400 ppm Nb, 10-3000 ppm Zr, 230-13,000 ppm F). Other types of REE deposits are found in New Mexico. Carbonatites are found in the Lemitar and Chupadera Mountains, Laughlin Peak-Chico Hills, Lobo Hill, and Monte Largo (Sandia Mountains). Disseminated Y-Zr deposits in syenite are found at Pajarito Mountain, Mescalero Apache Indian Reservation near Ruidoso. In 1990, Molycorp, Inc. reported historic resources of 2.7 million short tons grading 0.18% Y2O3 and 1.2% ZrO2 as disseminated eudialyte. Two additional deposit types have potential for REE in New Mexico: Cretaceous heavy mineral, beach-placer sandstone deposits and pegmatites. Exploration is ongoing in the Lemitar, Gallinas, and Cornudas Mountains. Many challenges face the mining industry in supplying REE. Most REE deposits are associated with radioactive waste material, which will require special handling. Future development of REE-based green technologies will be challenging and demand more research in many fields.

    A Concise History of Geological Maps: Beneath this Map, there is an Igneous Idea

    By David Bressan | March 29, 2014 |  Comments1

    In the 18th century the geological significance of volcanoes was (literally) a hot topic for naturalists – many considered volcanoes only as a local phenomenon, the visible fire feed by underground sulfur veins and the rocks found around them being the ashes of this combustion. Some naturalists considered volcanoes as natural valves of a large underground reservoir of molten rocks, once on the surface the molten mass solidified forming deposits of igneous – “fire-born” – rocks on a large scale, reshaping entire landscapes.

    Jean-Ètienne Guettard (1715-1786) was a pharmacist who got interested in geology studying the distribution of medical plants, as he noted that certain plants are restricted to areas where outcrops with certain rocks occur. In 1751 he visited the city of Vichy in the French region of Auvergne, where he noted that a black rock, quarried in the region, was widely used as building material. He recognized the rock of igneous origin, but if this rock was here to be found, where were the volcanoes from which it once poured out?

    Fig.1. Basalt columns used as bricks in a stone wall, village of Murat.

    Fig.2. Quarry with columnar basalt in situ, located near the village of Le Pont de Alleray.

    In the city of Clermont-Ferrand he was accompanied by a local naturalist in a visit to the mountain Puy de Dome (1.465m), here the two men recognized that Le Puys, a chain of mountains stretching from north to south, were in fact a chain of fossil volcanoes, the strange depressions on almost every summit were the eroded remains of the ancient volcanic craters. In 1751 Guettard published his observations, trying to convince his fellow naturalists of the ancient igneous origin of the entire area of today’s region of Auvergne – however skepticism prevailed.

    In 1763 the naturalist Nicolas Desmarest (1725-1815) decided to test Guettard´s hypothesis by mapping the region. As the rocks where once molten when pouring out from a volcano, he should find “flows” and these should be connected to a volcanic crater. Many contemporary naturalists had rejected the volcanic origin of the Auvergne region as many outcrops of rocks didn´t seem to fit this premise. However Desmarest recognized that isolated areas of igneous rocks were in fact eroded remains of once larger lava covers – the rivers had eroded the now missing parts, but by carefully mapping of elevation and position the isolated cliffs could be fitted in a pattern of lava flows. Desmarest was even able to reconstruct a time sequence (time is an important factor in a geological map) of lava flows, arguing that younger flows were situated higher as older flows, as the younger lava overflow already solidified rock.

    Fig.3. “Map of a part of Auvergne, representing the lava flows, where basalt is found in prismatic and round forms, for use in understanding the memoir by M. Desmarest on his basalt.” By Nicolas Desmarest (1725-1815) and François Pasumot (1733-1804), published in 1774, image in public domain. Desmarest was the first person to connect the dark rocks – mostly basalt – and volcanoes.

    Demarest’s map poses the interesting question if it could be classified as a true geological map. It depicts outcrops, connects these outcrops with a rock unit (which at the time was still a novelty) and even features a time sequence. However it only considers igneous rocks, showing them in an oblique landscape view (not as a topographic map).

    Most important is the idea behind this map – Demarest’s figure was still more a diagram than a map, connecting the dots (or outcrops) to form a line, pointing to the true origin of the rocks, as products from an extinct volcano.

    To be continued…

    Outlier Scientist Seeks Spotlight as New IPCC Report

    Outlines Climate Risks

    As hundreds of scientists work to come to consensus on a summary of global climate change impacts and vulnerabilities, an outlier scientist has sought a larger spotlight for his fringe views. The Working Group II (WGII) report of the Intergovernmental Panel on Climate Change (IPCC), to be released in Japan on March 31, highlights the grave risks we face as the climate changes. But some news coverage previewing the release has focused on the views of Dr. Richard Tol, an IPCC author who opted to withdraw from the author team drafting the report summary (known as the Summary for Policymakers) due to what he claimed were the “alarmist” nature of early drafts. In fact, the summary is a conservative portrayal of the state of climate science understanding.

    • Tol’s outlier views underscore the IPCC’s role as a consensus document, attempting to bring in as many diverse viewpoints as possible. That includes those such as Tol with connections to climate skeptic groups. Tol may have been dissatisfied with this process, but he had the same opportunity as any scientist.
    • The report ultimately reflects the fact that Tol’s work is outside the mainstream. According to a leaked copy of the current draft, the report finds that the impacts of climate change are and will continue to be negative. It doesn’t “conceal” the benefits of climate change in localized areas, but it makes it clear that the balance of impacts is harmful overall. The report also shows there are limits to the potential for adaptation.
    • The report shows how important it is to begin reducing emissions immediately. We’ve already caused some warming, and there’s more on the way. Our choice now is to reduce emissions and experience the impacts of moderate warming, or delay and experience extreme warming. Voices such as Tol that promote the “benefits” of warming are presenting a false choice.

    Impacts of warming are negative, both for agriculture and GDP.

    The WG2 draft report is clear that agricultural impacts of climate change are negative (Summary for Policymakers, p.3 line 15). The report doesn’t hide the fact that some areas will experience positive agricultural impacts, but it concludes that negative impacts will outweigh positive impacts on a global scale, now and into the future. A recent literature review backs up this claim, reviewing negative impacts on yield for warming of 2ºC. The report also concludes that crop markets are sensitive to climate extremes, judging by recent spikes in food prices following extreme events in key producer countries (SPM p.3 line 15).

    In interviews Tol has dismissed this finding, saying, “They will adapt. Farmers aren’t stupid.” But the report is also clear that adaptation carries costs and limits. For example, as warming approaches 4ºC, even the best adaptations will not be able to avoid serious threats to food security (WG2 SPM p.10 line 19). And this is occurring in a world where global demand for food is expected to increase.

    With respect to global GDP, the WG2 report offers cost estimates only up to 2.5ºC of warming. These impacts are negative, estimated to cost up to 2% of global income, which is acknowledged to be only a partial estimate. In fact, the costs of 2.5ºC of warming laid out in WG2 are something of a best-case scenario (or at least a reasonably good scenario), showing what will happen IF we take strong action to reduce carbon emissions. If we do not take action on climate mitigation, we could be experiencing around 4ºC of warming by 2100 according to the business as usual (RCP 8.5) scenario (WGI Annex II Table 7.5). That’s uncharted territory and possible even within the lifetimes of some who are alive today.

    Other estimates suggest the high impacts on global GDP with warming of 4ºC (For example the Stern Review found impacts of 5-20% of global GDP). GDP also does not fully account for humanitarian disasters to poorer countries. Extreme impacts in poor, tropical areas (which are expected to be the first to experience the most severe disasters) may not significantly affect global GDP because of the low standard of living – but they still matter. Reports like the World Bank’s Turn Down the Heat portray likely consequences for vulnerable populations.

    Discussing benefits of warming presents a false choice.

    Furthermore, even Tol acknowledges that warming will be detrimental at high levels, which is where we’re headed without climate mitigation. In fact, we may already be committed to half of the 3ºC of “moderate” warming that Tol believes will be beneficial. This means that our choice is between reducing emissions in order to experience moderate (rather than severe) warming, or doing nothing and experiencing severe warming, beyond 4ºC. As Tol wrote in a 2009 paper: “The climate responds rather slowly to changes in greenhouse gas emissions. The initial warming can no longer be avoided; it should be viewed as a sunk benefit.” Some are spinning Tol’s work to present a false choice between no warming and moderate warming, but this isn’t really an option available to us. Action now is advisable under any plausible climate scenario: the risks are simply too high to wait.

    The WGII summary is a consensus product with many voices.

    The IPCC included Tol as an author despite his connections to the Global Warming Policy Foundation, which has repeatedly attacked the IPCC, refused to disclose its funding sources, and promoted questionable science. But the report is a consensus document, and if the literature does not support a viewpoint, it won’t be emphasized. As Bob Ward, policy and communications director of the Grantham Research Unit on Climate Change and the Environment at the London School of Economics, told Reuters: “Of the 19 studies he surveyed only one shows net positive benefits from warming. And it’s the one he wrote.” As the author of the underlying chapter on economic impacts, Tol himself ended up detailing the negative net impacts of climate change. Yet, he is contesting a summary of the whole report that is consistent with the findings of his chapter. The real consensus shows that climate change is serious and detrimental, and we need to act now to stop it.

    Scientists’ latest study: Climate impacts felt ‘across all continents’

    Posted on March 28, 2014 | By

    coal

    A coal-fired power plants:  Coal burning is a major cause of climate change.  Use of coal in the United States is down, but China has overtaken the U.S. in greenhouse gas emissions.

    Climate change is being felt from the lowlands of Bangladesh to villages in the Arctic, with impacts ranging from droughts to the spread of disease to the melting of glaciers, according to a United Nations-sponsored report due for release on Monday.

    It is the latest work of the Intergovernmental Panel on Climate Change, with a final version being hammered out in Yokohama, Japan, by 66 scientist-authors and officials from 115 countries.

    “In recent decades changes in climate have caused impacts on natural and human systems on all continents and across the oceans,” said a final draft of the report, obtained by The Guardian newspaper.

    The report says “tipping points,” in which damaging impacts cannot be reversed, are fast being reached in both cold and warm corners of the Earth.

    “Both warm water coral reefs and Arctic ecosystems are already experiencing the regime shifts,” concluded the IPCC report.

    The IPCC shared the 2007 Nobel Peace Prize.  The report due out Monday is the second of three on impacts of climate on the planet.  The first, published last fall, cited “unequivocal” evidence that humans are the “dominant cause” of global warming.

    The latest report strings together very similar impacts in very different climates.

    It finds that the gravest immediate threat is to millions of people who live in low-lying coastal areas, as well as small islands — and island nations — who are vulnerable to both rising sea levels and storm surges.

    The New York Times, on Friday, published a long report on coastal flooding in Bangladesh, the densely populated, typhoon-swept Indian Ocean state.  Scientists in Bangladesh predict the country could lose 17 percent of its land by 2050, displacing 18 million people.

    Yet, in the far-off Alaskan Arctic, native villages are feeling impacts of climate change.  The ice pack, which protected them from fierce fall storms, is forming later in the year.  The result is that villages bear the full brunt of storms off the Bering Sea.

    The Seattle Times, in an exhaustive science-grounded report last year, detailed impacts of ocean acidification from New Guinea to the shellfish beds in coastal waters of Washington.

    “Once again, the science grows clearer, the case grows more compelling, and the costs in inaction grow beyond anything that anyone with conscience or common sense should be willing to contemplate,” said a draft of the IPCC report.

    The report indicates, for instance, that drought and flooding could reduce crops across the world by 2 percent per decade.

    Despite the “unequivocal” evidence, and calls to “common sense,” polls show that the political critics of climate change have made an impact on public opinion in the United States.

    The right-wing “echo chamber” of talk show hosts, Fox News pundits, and allies of Big Oil and Big Coal continue to spread doubt.  At times they have even used the same strategists who designed the tobacco industry’s campaign of doubt about cigarettes causing cancer a generation ago.

    Another “tipping point,” said the IPCC draft, is that climate shocks will soon no longer be seen as local crises.

    “The really scary impacts are when things start gelling together globally: If you have a crisis two or three places around the world, suddenly it’s not a local crisis,” Dr. Saleemul Haq of the International Institute for Environmental Development told The Guardian.

    The Pacific Northwest is facing a fundamental decision, namely whether to promote and enable Big Coal and Big Oil as both seek new markets in Asian countries where emissions are rising.

    As coal is supplanted by cheaper natural gas, and faces tighter regulations, coal companies are seeking rescue by developing new export markets in China for coal from mines in Wyoming and Montana.

    A coal train:  Montana and North Dakota want to send lots of them our way.

    Coal trains could be rumbling through Northwest cities if proposed export ports are developed at Cherry Point north of Bellingham, and at Longview.

    Huge proposed coal export terminals, proposed for Longview and Cherry Point (north of Bellingham), are undergoing environmental review.  Canadian producers want to increase exports out of Roberts Bank, a 1960s-vintage export terminal just north of the U.S.-Canada border.

    Two big pipeline proposals are working through Canada’s regulatory system.  The first, called Northern Gateway, would ship Alberta oil across northern British Columbia to an oil port at Kitimat, at the head of a long, narrow channel.

    The second is a proposed “twinning” — or more — of the existing Trans-Mountain Pipeline that extends from Alberta down to Burnaby, B.C., just east of Vancouver.  The expansion would be for export, meaning an estimated 34 tankers a month would travel the waters of Haro Strait between the U.S. San Juan Islands and Canada’s Gulf Islands.

    Tesoro is planning a oil terminal in Vancouver, Wash., that would receive oil by rail.

    The last IPCC report indicated the world would be safer if much of its remaining fossil fuel reserves remained in the ground, and clean energy sources developed.

    IPCC has gotten bolder in its predictions, as studies show climate impacts accelerating.  It did get in hot water over a 2007 prediction that Himalayan glaciers, a vital water source for China and the Indian subcontinent, could be gone by 2035.  Not so fast, but the glaciers are still retreating.

    Best:

    1. On Wednesday Bill gave a great speech about his values and Labor’s priorities at the National Press Club.

    You can watch Bill’s full speech here.

    2. I mentioned last week the Government was cutting payments to 1,200 children of war veterans, including orphans. Labor introduced disallowance votes in the House and Senate to stop the Government from cutting these payments.

    We won the vote in the Senate, which means those payments are protected, for now. Shamefully the Coalition voted against our motions, and for cutting payments to orphans. Full story here.

    3. Sir Tony Abbott, Prime Minister of her Majesty’s Loyal Executive Council for the Colony of Australia decreed the return of knights & dames to Australia’s honour system. Senator Sam Dastyari of South Wales New gave a speech that will outlast the empire.

    4. After stepping aside as Assistant Treasurer, Senator Arthur Sinodinos’ plans to repeal important superannuation protections put in place by Labor have been shelved by Finance Minister Mathias Cormann.

    When even Alan Jones is left supporting Labor’s position, the Liberals and Nationals have very few friends left.

    5. Bill Shorten and Tanya Plibersek reaffirmed Labor’s support for the Gonski school reforms by introducing a bill which would force the Government to keep its election promise that no school would be worse off under a Liberal Government.

    The Liberals and Nationals voted to stop the bill being debated. Labor will keep standing up for our teachers and students, even if Tony Abbott won’t.

    Worst:

    1. I wish this wasn’t true. In answer to a question from Senator Nova Peris, Attorney General George Brandis said: “People do have a right to be bigots you know”.

    Someone showed me the quote during Question Time only moments after he’d said it. My reaction was to ask if we’d checked the tape because it seemed too extreme to be true. Watch it the video here, it’s extraordinary. If the Federal Government won’t protect our citizens from hate speech, who will?

    If the Federal Government won’t protect our citizens from hate speech, who will?

    If the Federal Government won't protect our citizens from hate speech, who will?

    2. I was forced to introduce a motion of no confidence in the Speaker yesterday. Not since 1949 has the House moved a motion in this particular form.

    It’s not a decision I took lightly, but when parliament looks like a protection racket to protect Tony Abbott from answering any questions, something has to be done.

    3. Shadow Treasurer Chris Bowen showed that Joe Hockey has been cooking the books, adding $68 billion to the deficit in his first few months as Treasurer. We know what he’s up to. He’s trying to blow the deficit to justify his budget cuts.

    Labor’s onto his trick, and the Australian people will be too.

    4. If ever there was an example of something falling short of the hype, this is it. Tony Abbott proclaimed Wednesday was to be “red tape repeal day” complete with a bonfire of regulation.

    My favourite was the one about a mule or bullock being used for defence purposes. I’d love to know how repealing these laws makes a scrap of difference to any Australian business, but I am told there is precedent for cows with guns – check it out here.

    5. Have a look at what Christopher Pyne had to say within minutes of Tony Abbott claiming how grown up his government was.

    On a final note, Speaker Bronwyn Bishop established some new precedents in the Parliament this week.

    Mark Dreyfus is the first person in the history of Federation to be thrown out for saying “Madam Speaker” and Julie Collins became the first person since Federation to be thrown out for “infectious laughter”. In defence of Julie, Tony Abbott was talking about knights and dames, it was pretty funny. Photo by @mearesy.
