SGA 2009 Session B6 "Genesis of Iron Oxide-Copper-Gold Deposits"

This conference session, which involved oral presentations and poster displays, as well as an exhibition, was the 10th Biennial Meeting of the Society for Geology Applied to Mineral Deposits (SGA).

It was jointly convened by the SGA and the Economic Geology Research Unit at James Cook University, Townsville, in association with the Society of Economic Geologists, and was held in Townsville, North Queensland, Australia, from Monday 17 to Thursday 20 August, 2009.

The conference comprised two half day plenary sessions, one arranged by the SGA, the other by the SEG, followed by more than 210 oral presentations divided among 21 technical theme sessions, run concurrently over the remainder of the four days. The conference was followed by a number of short courses and field trips.

Mike Porter of Porter GeoConsultancy Pty Ltd, Louise Corriveau of Natural Resources Canada, Geological Survey of Canada and Fernando Tornos of the Instituto Geológico y Minero de España were invited to convene session B6, "Genesis of iron oxide-copper-gold deposits", which was run on Thursday 20 August, 2009. It comprised 12 oral presentations and 7 posters, as listed below. Each presentation and poster has a three A4 page extended abstract in the two volume conference proceedings, reviewed by the convener panel.
