Expertise and Research Interests
I have used mineral chemistry as a tool to understand the role of hydrothermal fluid circulation in two important mineralizing environments in Canada: the Sudbury structure (ON), and the Ferguson Lake deposit (NU), both of which are important sources for Ni, Cu, and platinum group elements. I have also worked with industry geologists for a research project on Geochemical and Mineralogical Halos around Magmatic Sulfide Deposits. My experience also includes the study of black shales using whole rock geochemistry, in order to understand their tectonic environment of deposition and its potential relationship with Colombian type emerald mineralization. In addition, I have also worked for the oil industry in various projects in the upper Magdalena Valley (Colombia) and the Maracaibo Basin (Venezuela), involving petrography, clay mineralogy and fluid inclusions studies
Other Expertise
Previous fields of expertice encompass diverse aspects of Geochemistry and Economic Geology such as: geochemistry of black shales and clastic sedimentary suites directed towards understanding their relation with provenance and tectonic setting at the time of deposition, the genesis of the black shale hosted Colombian-type emerald mineralization, clay mineralogy and illite crystallinity as indicator of diagenesis and low-grade metamorphism, characterization of mineralizing fluids in hydrothermal veins and quartz overgrowth associated with diagenetic processes and Geothermal geology and fluid geochemistry directed at investigating, assessing and utilizing geothermal resources.
Future Research
Use trace and isotopic geochemistry of minerals and fluid inclusions in combination with field mapping and petrography to study:
Hydrothermal alteration and water-rock interaction in fossil hydrothermal systems and their relation to ore forming processes.
The Magmatic-Hydrothermal transition.
The role of hydrothermal fluid flow around massive sulphide mineralization and the consequences for mineralization, alteration, and geochemical dispersion.
Characterization of mineralogical and chemical halos as tools for deciphering mineral occurrences.
Genesis of ores and ore deposit exploration, specially exploration of Ni-Cu-PGE deposits and understanding of the role of hydrothermal fluids in the modification (redistribution and concentration) of Ni-Cu-PGE ores.
