Background

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
  • Cenozoic Magmatism in North East Brazil and in South East Queensland
  • U-He, 40Ar/39Ar, and Re-Os as fingerprints of metal sources in orogenic gold deposits
  • U-Th/He dating of iron and manganese oxides
  • Cosmogenic 3He generation and retention in goethite and hematite
  • Hydrothermal vs. supergene origin of orebodies in banded iron formations in the Hamersley iron province, the Quadrilátero Ferrífero iron province, and the Carajás iron province
  • Supergene Enrichment in the Kalahari Manganese Fields, South Africa
  • Timing of topaz, emerald and gold mineralization
  • 40Ar/39Ar geocronological constraints on postulated hominid fossil sites in Cueva Victoria, Spain
