Noble Metals, Subcontinental Lithosphere, and Ni-Cu-PGE Deposits

Recent research by Kamenetsky et al. published in Geology provides insight into the nature of the parental magmas potentially responsible for the formation of nickel-copper-platinum group element (Ni-Cu-PGE) deposits in intra-plate environments.  Previous researchers have illustrated the importance of the … Continue reading

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

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

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
