Abstract
The Giles Plutonic Complex is briefly described. Volcanics occurring in the same tectonic setting are thought to be the extrusive silicic differentiates. Evidence is presented for a differentiation of the parental magma prior to its subsequent intrusion into higher levels where it produced fractionally crystallised rock series. The Volcanics display chemical similarities to other silicic differentiates associated with plutonic basic complexes and the province as a whole has a bimodal character.
