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, Sn-W-Mo-Au granophile systems including their related skarn systems. Of particular interest lately 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 emmisions and related volcanologic implications.
