The contribution of geochronology to understanding the paleozoic geological history of Australia
From the viewpoint of isotope geochronology, studies of the Paleozoic geological history of Australia can be divided into three main eras: (i) the era of stratigraphy, when the ages of igneous and metamorphic events were inferred primarily from stratigraphic relationships; (ii) the era of K-Ar and Rb-Sr, when the broad time frame of many of the main thermal events was mapped out; and (iii) the era of SHRIMP, when U-Pb microanalysis, in combination with techniques such as Ar-Ar, Sm-Nd and Lu-Hf,...[Show more]
