Associate Professor Paulo Vasconcelos' research is in the fields of: Low-T Geochemistry, Economic Geology and 40Ar/39Ar Geochronology. He received his PhD from The University of California (Berkeley). Paolo Vasconcelos research interests cover - Supergene enrichment in ore deposits
- Isotopic dating of weathering processes
- Exploration geochemistry
- Palaeoclimatology and landscape evolution
- Application of K-Ar and 40Ar/39Ar and noble gas systematics to ore deposit genesis
- Origin and geochemistry of gem deposits
His chief research projects are in the areas of:- Weathering Geochronology, Weathering Geochronology and Landscape Evolution
- Mechanisms and timing of silicification in Australia and the genesis of opal deposits
