Current research interests

I am interested in an array of complex magmatic-hydrothermal mineralizing and alteration processes, associated with the formation of massive-sulphide deposits (Bathurst Camp), porphyry Cu-Mo-Au systems, and Sn-W-Mo-Au granophile systems including their related skarn systems, as well as IOA (Iron Oxide Apatite) and IOCG (Iron Oxide Copper-Gold, REY, U) systems.

Of particular interest are the complex assimilation (syntexis and volatile fluxing of limestone-marbles by magma(-vapour) processes and their implications for mineralization processes, enhancing vapour saturation and solidification (endo- & exo-skarn reactions), as well as their implications for secular atmospheric CO2 emissions and related volcanologic implications.
