Fall 2018
The Steen River impact structure (SRIS) is a buried, complex crater located in NW Alberta, Canada. It was discovered in the mid 1900’s and was initially thought to be an endogenic igneous intrusion. With the growth of impact studies on Earth and other planets, the SRIS was recognized as such in...

Controls on Solubility and Deposition of Quartz, Calcite, Fluorite and Anhydrite in Boiling Saline Hydrothermal Systems
DownloadSpring 2022
Fluid boiling is a key mechanism for precipitation of minerals in epithermal deposits, and evidence for boiling includes a variety of vein mineral textures that indicate rapid deposition. Hence, the relationships between vein mineral paragenesis and boiling are critical to interpreting processes...

Genesis and controls on mineralization at the Hammer Zone silver showing, Mount Mye Trend, hosted by the Anvil Batholith, South-Central Yukon
DownloadFall 2017
When Silver Range resources acquired the Keg property in 2010, one of the prospects included was the Hammer Zone. Ensuing mapping and surface sampling found the Hammer Zone to be a small, bonanza-grade, epithermal silver system contained entirely within the Anvil Batholith. Initial petrographic...

Geochemistry and Mineralogy of the Silver Pond Prospect in the Toodoggone District: Implications for Regional Exploration
DownloadFall 2022
The Lawyers Property located in the Toodoggone district hosts a well-known extensively explored low sulfidation style epithermal deposit as well as an adjacent less understood target area known as Silver Pond that shares characteristics of a high sulfidation style system. The Silver Pond prospect...

Spring 2016
This contribution presents the results of a new mapping and geochemical investigation of well-preserved rock units in the Acasta Gneiss Complex (AGC), Canada, and provides additional support for a broadly mafic Hadean Earth, in which the first evolved crust formation took place in a geodynamic...

The application of detrital zircon grains from Pleistocene eskers for reconnaissance bedrock mapping in the Acasta Gneiss Complex
DownloadFall 2019
The Acasta Gneiss Complex (AGC) is a ~2400 km2 Hadean-Mesoarchean terrane that contains the oldest known zircon-bearing rocks on Earth. Despite its importance for early Earth geology, only a small fraction (~50 km2) has been mapped in detail. To determine the lateral extent of ancient rocks and...
