Resumen
NE Queensland, Australia is characterized for hosting abundant magmatic-hydrothermal mineral deposits related to Carboniferous and Permian magmatism (Henderson, 1980; Champion and Bultitude, 2013).
Some of these deposits are located in the northern tip of the Bowen Basin, 150 km south of Townsville.
Evolution Mining holds the ground of the Mt. Carlton district that includes the only deposit currently in production, the Mt. Carlton Au-Cu-Ag deposit (Sahlstrom et al., 2018), and several other prospects of porphyry copper, high-sulfidation and low-sulfidation epithermal type mineralization.
In this study, we present a detailed chronostratigrapy based on newly obtained LA-ICP-MS U-Pb zircon dating in order to distinguish the different volcanoplutonic events through time. Additionally, we also provide a new and complete geochronological work on the different mineral prospects based on step-heating Ar-Ar (alunite, illite and adularia), to correlate volcanoplutonic stages with mineralization events.
