Earthquake-Induced Geochemical Anomalies

Posted on May 7, 2013 by stevepiercey

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 →

Classic papers in Economic Geology: Fallick et al. (2001) – Bacteria were responsible for the magnitude of the world-class hydrothermal base metal base metal sulfide deposit at Navan, Ireland

Posted on April 30, 2013 by stevepiercey

Irish-type zinc-lead deposits represent a distinctive sub-class of the carbonate-hosted zinc-lead deposit family, having geological features and genetic models that are hybrids between sedimentary exhalative (SEDEX; also known as clastic zinc-lead deposits) and Mississippi Valley-type (MVT) deposits.  They are important … Continue reading →
