M.S. Thesis Defense by Patrick Quillen—April 20 

Buffalo Canyon: An Oligocene Greisen-Like Reduced Intrusion-Related Gold Deposit in the Union Mining District, Nye County, Nevada
Advisor: Dr. John Muntean
Thursday, April 20th at 1:00 p.m., LME 415

You are invited to attend Patrick Quillen’s defense this Thursday, April 20th, 2017LME 415. 1:00 p.m.
Parking at UNR

Buffalo Canyon is a gold prospect located near the historic Berlin mining area in the Union district of northern Nye County, Nevada. LA-ICPMS dating of zircon (U-Pb) from 11 samples reveal three distinct periods of magmatism – in the late Jurassic (162 to 158 Ma), the late Cretaceous (83 to 77 Ma), and the Oligocene (25 to 24 Ma). Oligocene intrusive rocks are intermediate to felsic, metaluminous to weakly peraluminous and locally ilmenite bearing. Muscovite + tourmaline alteration is locally pervasive within Oligocene intrusions.  Mineralization is defined by free gold-bearing, sheeted, crack-seal quartz veins that locally contain muscovite, tourmaline and fluorite within veins and as envelopes. Veins have a Au-Te-(Mo-Bi-Sn) elemental association, high Au:Ag ratios (>1:1) and are hosted in both hornfelsed country rocks and weakly in Oligocene intrusions. Veins contain common hypersaline brine and coexisting vapor-rich fluid inclusions, which combined with thicknesses of coeval Oligocene volcanic rocks suggest estimated paleodepths of < ~3 km for deposit formation. Mineralization strongly resembles typical reduced intrusion-related gold systems that are well defined in Alaska and Yukon, but only a few examples have been documented in Nevada.

DGSE Colloquium Speaker Series—April 3

DGSE Colloquium Speaker SeriesApril 3:
Dr. Daniela Rubatto (U Bern, Switzerland)
Mineralogical Society of America, Distinguished Lecturer

A message from Philipp Ruprecht, UNR Dept. of Geological Sciences & Engineering (DGSE):
Dr. Daniela Rubatto will be giving two talks on Monday April 3.
Technical talk at 9:30-10:30 AM in LME 425 at University of Nevada, Reno. (Everyone interested is welcome.) “The tale of the tiny: petrology, geochemistry and geochronology of U-Pb accessory minerals”

The tale of the tiny: petrology, geochemistry and geochronology of U-Pb accessory minerals

For decades accessory minerals containing traces of the radioactive elements Th and U have been used for reconstructing crustal processes. Minerals such as zircon, monazite, allanite, rutile and titanite are robust geochronometers and isotopic tracers. Additionally, these minerals incorporate many other trace elements that provide information on the conditions of formation. Therefore, U-Th accessory phases provide important links between geochronology, petrology and geochemistry. Decoding the wealth of information these minerals preserve requires a variety of methods and approaches. As these accessory minerals are tiny and often contain multiple domains, in situ analysis with high spatial resolution is required. The interpretation of any data acquired from these accessory minerals demands an understanding of their behaviour during metamorphism and melting, and the evaluation of decoupling of the different chemical and isotopic signals.

This lecture will review recent developments in petrology and geochemistry of U-Pb accessory minerals. They form in a variety of rock types under conditions as variable as diagenesis to deep subduction, melt crystallization to low temperature alteration. Processes of formation include precipitation from aqueous fluids and melts, metamorphic reactions involving other phases, and alteration and sub-solidus modification of pre-existing crystals. These processes lead to distinguishable textural, chemical and isotopic characteristics of specific mineral growth zones that are powerful links to their petrogenesis.

DGSE Seminar at 4 pm in DMS 102:
“Fast and furious or slow and steady: rates of subduction and crustal melting”

List of other confirmed seminar speakers for Spring 2017:
04/24 Dr. James Dolan (USC) – Slemmons Lecture
05/01 Dr. Keith Priestley (Cambridge, UK)

These talks are at the usual location in DMS 102 at 4 p.m.
