New SHRIMP U-Pb zircon ages from Tasmania New SHRIMP U-Pb zircon ages from Tasmania

New zircon U-Pb geochronological data was obtained via Sensitive High-Resolution Ion Micro Probe (SHRIMP) from six samples of granitic rocks: five from the Eastern Tasmania Terrane and one from the Western Tasmania Terrane.

The SHRIMP zircon U-Pb analytical program was conducted using high quality zircon separates, mounts, photographs and cathodoluminescence images. Data were obtained during 2012-2013, under a collaborative Geochronology agreement between Mineral Resources Tasmania (MRT) and Geoscience Australia (GA).

The primary objective of this study is to refine the regional chronology of mid-Paleozoic felsic plutonism in Tasmania. In some cases, the samples were chosen because of economic importance, or to help resolve regional problems.
