Wildcat Silver has just announced positive pre-feasibility study results from its Hermosa project, near the small town of Patagonia in Santa Cruz County, Arizona. According to the press release: The pre-feasibility study includes the contribution from the projects’ two primary metals, silver and electrolytic manganese metal (EMM), and three by-product metals, gold, zinc and copper.
Nice publications on the geology of gemstones are rare. Here is a nice open file report from the Yukon Geological Survey. It is Open File Report 2004-10, “EXPLORATION CRITERIA FOR Coloured Gemstone Deposits in the Yukon” by Lori
If you are looking for a last minute Christmas present, these shoes might not be the right choice. Also, I am not exactly sure if it’s too nerdy, but the idea is great and the shoes are beautiful. Think about … Continue reading
I ran into a friend after many years. Her son used to come to our academy for soccer and rugby coaching. She mentioned that a common friend had recently put up a link to my blog on his Facebook wall and after reading a few of my posts had showed my blog to her son, reminding him who I was.
Her son who is now a teenager exclaimed.. "but Mama how is it that a rugby coach can be clever enough
Like some of the others, this seems far away from most of the action, and the deep geologic structure as I have guessed it. Unlike Texas, I have good faith in the location. To me, it just shows how close is the general stress field to be triggered. I can't imagine the geology required to have an infinite number of M3's without an M4, but I am now going to tempt Fate by issuing a
In the past three or so years as Archivist to the Society, a good proportion of the enquiries I receive concern the major figures of geology and science. You know, those upright, moral Fellows who have made substantial contributions in … Continue reading
Follow some of the Utah Geological Survey’s Paleontologists and volunteers as they explain the geology, discovery, and extraction process at the Doelling’s Bowl
“We’ve done study after study…the geology is spectacular,” says Kraemer. “It’s in proximity to the lake, but not really part of its system…Any water that is at that level has been there for 500 million years since the Great Lakes basin formed.”
For the sake of my mental health, I don't say much on this. The proof will be in the pudding of the excavation.
Review: Australia, The Royal Academy If you’re in London for a spot of Christmas shopping and fancy at least a visual winter warmer, head to the Royal Academy’s Australia exhibition (till 8th December). The exhibition spans more than 200 years … Continue reading
What better alcohol to follow up last entry's Earthquake with than this liqueur - After Shock.This is a product of the Jim Beam company with several varieties. The main one I am aware of (and the one pictured above) is the Hot and Cool Cinnamon version. It is a rather strong drink (80 Proof) with a strong cinnamon taste. Nice as a shooter and great sugar crystals when everything is all
Interesting!... In the Research Focus section of Geology Andrew G. Tomkins writes about (open access) the current state of understanding on the sources of orogenic gold deposits. These are deposits formed in accretionary and collisional orogens where two tectonic plates are pushing against each other.
On the source of gold in such settings:
There are two plausible sources for the gold:
For most of us who are not very familiar with the exact duties of each scientific profession, the differences between geologists and engineers seems rather obvious since each profession has its own educational requirements, emphasizes a different area of science and most important has different titles. One is a geologist and the other is an
This article is reblogged from Lee Allison’s http://arizonageology.blogspot.com/ The Arizona Mining Association reports that “Mining activity in 2012 generated $4.8 billion in total income for workers, business and property owners, and governments across Arizona, as well as, accounting for 12,100 direct jobs through the payrolls of mining companies. Indirectly, mining generated an additional 40,000 jobs
Close observers of this space may have noticed that the title of geology.about.com—the line at the very top of the browser—now says "geoscience" rather than "geology." For many years I've insisted on the word "geology" to cover all the ground of Earth-based science. I've thought of "Earth science" as a sort of interloper, a newfangled, dumbed-down substitute. But I'm not always right. Sometimes, the rest of the world is right....Read Full
I was flipping through John McPhee 's Assembling California and came across this passage:
Gradually, though - outcrop to outcrop, roadcut to roadcut - Moores revived enough related scenes in the distinct origins of the random rock to frame a cohesive chronological story. That is what geologists do. " You spend a lot of time working over rocks and you have a lot of time to do nothing but
Really, we are well beyond the mere 'carbon warms us' crap, and must focus directly on the magnitude of the carbon sensitivity. This value, which I call Cs (I've never seen anybody couch it as a constant) must be somewhere between 0 and a heck of a lot.
First, we should consider the precision to which we can ever calculate it. Obviously, it must have more significant digits
Geology is, by nature, a field-based branch of science, and making on-site sketches is the best way to approach an outcrop. Why? Because field sketching sharpens your senses and turns you into a much better observer. It forces you to … Continue reading
I was at the 31st edition of the National Association of Petroleum Explorationists (NAPE) annual conference and exhibition which held from the 10th-14th November . This was my first experience of this largest gathering of Nigerian geoscientists related to the Petroleum Industry and it was an opportunity to feel the pulse of the Nigerian oil industry … Continue reading
Cabinet of curiosities proudly presents… This Week Geohistory: November 15, 1835: the “RMS Beagle” arrives to Tahiti, where a geologizing Darwin tests his famous reef-evolution-theory November 14, 1797: Birthday of Sir Charles Lyell, he is best known for introducing uniformitarianism in geology, however he was also interested in the enigmatic origin of Loess, a windblown
Here again we are drilling in Al-Namas, Saudi Arabia for geotechnical purpose and I am musing on samples for geologic purpose. Namas is a small town on the Arabian Shield. I still do not figure out the best catchy title for this blog series, but I think the current name give me a wide range to … Continue reading
