The emplacement of acid magma in the epizone, and the relationship with ignimbrites, North Queensland, Australia
Authors / CoAuthors
There is an aggregate outcrop of 12,000 square miles of Permian-Triassic acid igneous rocks inland from Cairns and Townsville, North Queensland. The rocks consist of ignimbrite and rhyolite, which are structurally and magmatically related to three high-level intrusions the Herbert River, Esmeralda, and Elizabeth Creek Granites. This report describes the emplacement of the acid magma in the epizone, and the relationship with the ignimbrites.
