The differing metallogeny of Accretionary v. Andean arcs

The differing metallogeny of Accretionary v. Andean arcs


aig_cdphrs02_1The Centre for Exploration Targeting (CET) is pleased to invite you to a Guest Lecture in the CET Seminar Series given by Tim Ireland.

Generative exploration demands that we predict what might be there on the basis of a proxy datasets that we believe to indicate something about processes we believe we understand. One such belief developed on the basis of Andean geology was that the porphyry Cu metallogeny of convergent margins improved as the arc matured and underwent sustained compression. That hypothesis applies poorly to the accretionary margin arcs of eastern Europe, Central Asia and British Columbia, and provokes a new exploratory look at the interplay between tectonics and 4D fertility for Cu, Au and PGE in convergent margin environments.

Speaker:

Tim has been playing geologist since he was a child, scrabbling around the abandoned copper mines of the Flinders Ranges looking for pretty obscure minerals. He worked as an exploration field assistant in the NT before completing a BSc at the Uni of Tasmania and a research project at McArthur River. Returning to UTas several years later, he completed a PhD investigating the district geology and structural controls on porphyry Cu deposits at Collahuasi, Chile. Tim has worked in gold and base metal exploration for 13 years, mostly in South America, the Tethyan and Central Africa, and is presently the Principal Geologist for Generative Exploration at First Quantum Minerals.
