Project Title: 
Regional pyrite chemical study on Iron Oxide Copper Gold deposits in northern Chile.
Project Abstract: 
Iron Oxide Copper Gold deposits (IOCG) are an important source of copper and gold, occur in a number places globally, but are poorly understood. These deposits are exploited in northern Chile, and are economically important, particularly because they are located relatively close to the coast. Recent work (by this author) on the IOCG deposits in the Candelaria-Punta del Cobre district have shown that important sulfide minerals that are associated with mineralization, such as pyrite, are chemically zoned from the core to the edge. This chemical zonation could potentially indicate that more than one magmatic-hydrothermal event occurred in the district, which if verified would represent an important advance in the understanding in this deposit, and with possible implications for deposits elsewhere. The purpose of this fieldwork is to collect a large suite of samples with the hope of finding more zoned pyrite samples from other IOCG deposits in northern Chile.
