Craton-scale controls and time-space distribution of IOCG and gold systems in the Gawler Craton

Skirrow, R.G.

Abstract

This talk outlines three key regional geological features considered to be essential for development of major iron oxide copper-gold systems in the Gawler Craton. They are as follows: 1. A plumbing system, comprising crustal-scale structures that developed during Palaeoproterozoic orogenesis along the margins of the Archaean core of the Gawler Craton. 2. Coeval timing of IOCG hydrothermal activity and Hiltaba-GRV magmatism at ~1575-1595 Ma. Anomalous high heat input to the crust, resulting in particular igneous rock compositions and high-temperature IOCG alteration at ~1575-1595 Ma
