“…Eskenazy (written communication), suggests that the tungsten mineralization is associated with nitrogenbearing thermal waters containing detectable tungsten that flow from geothermal springs in the vicinity of tungstenmineralized granitoids. A similar geothermal correlation to tungsten is discussed by Ririe (1989).…”

“…Data suggest that a lake fed by geothermal waters, possibly with some similarities to Searles Lake, California (Ririe, 1989;Carpenter and Garrett, 1959), formed in the Dall River-Coal Creek area, thus accounting for the water-lain nature of the mineralized mudstones and tuff. Present-day mud and brine at Searles Lake contain up to 118 ppm WO 3 .…”

“…It is densely vegetated and features very little bedrock exposure. Little was known of the geology prior to the pipeline construction in 1975-1977. Investigations of mineral resources in the region, including this project, were conducted intermittently by the U.S. Bureau of Mines (USBM) between 1975 and1989. This report, in process at the time of USBM's dissolution (1994), is one of a series of investigations to examine possible resources of strategic and critical minerals in Alaska.…”

Evidence for geothermal tungsten & germanium mineralization in Eocene coal and associated sediments, Fort Hamlin Hills, area, interior, Alaska

Eocene-age coal and associated mudstones near the Fort Hamlin Hills in central interior Alaska are highly enriched in tungsten and other metals. Coal is found in small, semi-closed basins along the Ray River to the west of the Fort Hamlin Hills and the Dall River. Metals are most concentrated in calcium-rich coal ash; tungsten, germanium, and lead are each found to range as high as 1 percent or more. In addition, gold, gallium, and uranium are generally elevated, and most samples contain anomalous zirconium and rare-earth elements. Coal in the Fort Hamlin Hills area has an apparent rank of high-volatile, lignite A to subbituminous B, and generally has a 6-10 weight percent ash yield. Maceral composition is dominated by vitrinite. Higher metal values occur in high-sulfur (>1.4%) coals in the Ray River valley as compared to unmineralized low-sulfur (<0.2%) coal in the neighboring Dall River valley. Mudstones that lie stratigraphically above the coal deposits in the Dall River valley generally contain 50 to 190 ppm tungsten. Microprobe studies suggest the mineralization found in coal of the Ray River mostly occurred in peat beds prior to, or concurrent with, diagenesis and coal formation. Mineralization is likely related to geothermal activity associated with rifting in a granitic terrane and volcanism. Water samples from present nearby hot springs contain anomalous levels of tungsten. Mineralization in peat accumulations or coal was likely accentuated due to Oligocene fissure basalts that entrapped the geothermal waters in the coal-forming section. Mudstones in the Dall River valley containing tungsten likely formed as Eocene-age lacustrine deposits in shallow lakes fed by geothermal water and intermittently covered by ash falls.

Seawater signatures in the supracrustal Lewisian Complex, Scotland

2022

View full text Add to dashboard Cite

Marble in the supracrustal rocks of the Lewisian Complex, Tiree, includes chlorine-bearing amphiboles, chlorine-rich apatite, sulphur-rich scapolite, albite and phlogopite, all of which are regarded as evidence for evaporites in other metamorphosed sequences. Titanite yields U–Pb ages of ∼1.6 Ga, i.e. late Laxfordian, which excludes a younger imprint of sodium metasomatism. Traces of anhydrite, and isotopically heavy pyrite, also indicate deposition from seawater. Elsewhere in the Hebrides, tourmaline in Lewisian Complex marbles may represent seafloor exhalative deposits. Combined, the evidence suggests Lewisian Complex supracrustal marbles formed in an evaporative environment, like other Palaeoproterozoic successions across the North Atlantic region.

“…The most notable deposit is the Searles Lake deposit in California, USA, where tungsten concentrations in the brines are as high as 56 mg/L (Altringer et al, 1978). The Searles Lake deposit is thought to have formed over thousands of years during the Pleistocene via endoheric termination of rivers eroding Wskarn deposits in the Sierra Nevada mountain range, and tungsten may also have been sourced by hot springs in the Sierra Nevada (Ririe, 1989). A map of the global distribution of tungsten deposits is shown in figure 2.1.…”

The first of many thank-you's goes to my supervisors, Heather Jamieson and Matt Leybourne, for their mentorship, guidance, and patience over the past few years. I am extremely privileged, honored, and proud to be part of the Jamieson Clan and the QFIR family, and couldn't have asked for a more wonderful group of people to develop my career as a geochemist with. The Winter Wonderlands, defense parties, and Grad Club beer discussions were some of the highlights of my time at Queen's. Heather, I fell in love with the north during our trip to Cantung, and our long, beautiful drives to and from the mine will be forever in my mind. Thank you so much for giving me this opportunity, and for the opportunities that have stemmed as a result from completing this thesis. Matt, your contributions to this thesis are innumerable. Having access to world class analytical facilities at QFIR, and same-day access to a worldclass geochemist for answers to my (often redundant) questions has been invaluable. Both of you held infinite patience during periods when I was low, and I honestly don't think my thesis would have been completed without your understanding. It has been a pleasure working with both of you. This thesis is dedicated to Kurt Kyser, who took me under his wing that one fateful summer in Kingston. After expressing my interest in geochemistry, Kurt offered me a summer student position at QFIR and exposed me to my first taste of analytical and field work, which lead to me completing an undergraduate thesis under his supervision. Kurt's enthusiasm for science, his lust for life, and his dedication to QFIR inspired me to pursue a career in geochemistry, and even more so to pursue a life of passion. I wish you could have reviewed this thesis, that we could've share the excitement of the results, or even just to have seen you shake your head and say, "nah". This thesis wouldn't be possible without Hendrik Falck, the Cantung connoisseur. Thank you for assisting with field work, and for sharing your big-brain knowledge of the Cantung deposit, of the history of the mine, and of the physiography of the Flat River valley. A brewpub visit in is order during my next visit to Yellowknife! A very special thank-you is in order for Dan Layton-Matthews, who first sparked v my interest in geochemistry via ternary diagrams in second year petrology, and another to Noel James for our discussions about big-picture global issues, science and creativity, and for just being a rad dude. Guy Narbonne, thank you for taking care of me when I got sick in Namibia, and for expressing not even the slightest discontent about missing part of the Etosha safari. Rob Harrap, I don't know how to express my thanks to you. We've had so many discussions throughout my undergraduate and master's degrees about anything and everything, but the ones where I came in distressed and left with some clarity are undoubtedly the most important.To all of the QFIR family, thank you for all of the analytical assistance, the laughs, and the wine over the years. April, your bubbli...
