This book was released on 2018 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold is a noble metal that has fueled mineral resource exploration in the Northern Great Basin and profoundly affected the national economy. The origin of the gold deposits has been at the center of basic and applied research, with the goal to develop refined exploration models. For the first time, I am able to unambiguously constrain the nature of electrum from a low-sulfidation epithermal deposit in the Northern Nevada Rift. In this study, the highly siderophile elements (HSE; Os, Ir, Ru, Rh, Pt, Pd, Re and Au) serve as an innovative tracing tool due to the inherent relationship between the HSE and Au that can be used to trace the origin of electrum directly. Coupled precise 187Os/188Os compositions and isotope dilution HSE abundance data are reported for electrum grains from the Fire Creek Mine, as well as for a suite of host rocks that encompass the bimodal basalt-rhyolite volcanism of northern Nevada. The mid-Miocene bimodal host-rocks have Os isotope compositions consistent with crustal contamination observed in the Columbia River Flood Basalt (CRFB) province. The host rocks are isotopically similar to the CRFB Wannapum, Grande Ronde, and Imnaha basalt formations. Highly siderophile element concentrations are heavily fractionated for the host rocks but are less fractionated for the electrum. Rhenium-Osmium isotope analysis of electrum yields a relatively unradiogenic initial 187Os/188Os of 0.1588, demonstrating a source distinct from the crust and that can only be of mantle origin. From this, I estimate that as much as 96% of the gold in the Fire Creek deposit is of mantle origin, in contrast to evidence for much larger crustal contributions from proxy measurements.

Download or read book Origin of Basalt-hosted Epithermal Gold-silver Mineralization in the Fire Creek Deposit, Northern Nevada Rift from a Whole-rock to Grain-scale Perspective written by Jorge Perez and published by . This book was released on 2013 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire Creek, located in northern Nevada, is host to a low-sulfidation, epithermal Au-Ag deposit that is spatially and temporally associated with mid-Miocene volcanism. This study implements a whole-rock to mineral-scale analysis in order to evaluate the ore's paragenesis. Volcanic units at Fire Creek are a co-genetic suite of basalts to trachydacites which were subjected to three distinct pulses and possess Au-Ag in two distinct forms. Two generations of gold and Ag bearing sulfide grains are present and the average Au varies from 28.3-6.7 ppm; Ag varies from 46.6-33.0 ppm. Other studies on mid-Miocene northern Nevada low-sulfidation epithermal Au-Ag deposits have reported general conditions for deposition or have focused on rhyolitic-hosted ores. These studies lack in-situ trace- and major-element analysis in order to provide a high precision model on mid-Miocene low-sulfidation, epithermal Au-Ag deposits. This study presents the first known highly siderophile element (HSE) analysis on electrum (Au and Ag alloy) grains and has coupled textural observations with in-situ chemical analysis in order to characterize individual pulses and develop a general paragenesis for northern Nevada mid-Miocene epithermal deposits.
