Application of spectral tools to iron ore exploration

•Describe two case studies that demonstrate how spectral surveys have helped geologists to understand and map mineral zonation associated with iron ore (Rocklea Dome and Weld Range)
•Discuss recent and future advances in spectral studies

Magmatic Differentiation Processes (Fractionation, Assimilation, Recharge) in Deep and Highly Dynamic Arc Magma Chambers

• Evidence that distinguishing chemical characteristics of copper ore- forming arc magmas develop during compressive orogeny
• Evidence that Cu-fertility developed at pressures near the Moho
• How Cu-fertile magmas acquire exceptional contents of H2O...

Magmatic Mineral Systems

Research on magmatic mineral systems has seen crucial advances in the past, but only incremental progress recently, why?
• Traditionally, the study of magmatic mineral systems has been carried out solely by petrologists and geochemists
• Insular approach,...

Porphyry Cu deposit

(1) The fertile porphyry intrusions are usually late in the evolution of a given volcanoplutonic suites;
(2) The fertile porphyry intrusions usually contains hornblende phenocryst, whereas earlier barren intrusions are mainly plagioclase-pyroxene phyric.
(3) The fer...
