Earthquake-Induced Geochemical Anomalies

A recent review article by Cameron illustrates the importance of earthquakes in the generation of geochemical anomalies above buried mineral deposits.  The paper builds on previous work by Cameron and colleagues (e.g., Cameron et al., 2002; Cameron and Leybourne, 2005; Leybourne … Continue reading

Bacteria, Oxygen, and Gold!

New research published in Economic Geology by Tomkins provides insight into the importance of atmospheric evolution and bacteria in controlling the distribution of orogenic gold deposits (and resources) during the planet’s history. Orogenic (mesothermal) gold deposits form from gold-bearing fluids that are … Continue reading

Instant gold

My inaugural posting. An article just recently published online in Nature Geoscience provides new insights into the origin of vein-hosted gold sytems (orogenic or ‘mesothermal‘ gold in the geological literature).  Weatherly and Henley have proposed ideas that link fault systems, … Continue reading
