Classic papers in Economic Geology: Campbell and Naldrett (1979) – The Influence of Silicate-Sulfide Ratios on the Geochemistry of Magmatic Sulfides

Posted on May 15, 2013 by stevepiercey

Magmatic sulfide deposits are critical sources of nickel (Ni), copper (Cu), and platinum group elements (PGE) globally.  These deposits form from the segregation of a sulfide liquid from a silicate liquid, similar to oil separating from water, due to the … 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 →

Classic Papers in Economic Geology: Hekinian et al. (1980) – the first description of seafloor massive sulfide deposits

Posted on April 8, 2013 by stevepiercey

This is my first post in the classic papers series.  I have a passion for volcanogenic massive sulfide (VMS) deposits, so I thought it would be fun to write a short blog on a classic paper that described and documented … Continue reading →
