Multiple intrusions and remelting-remobilization events in a magmatic arc: The St. Peter Suite, South Australia

Popis výsledku v původním jazyce

Granitoids with juvenile signatures are common in arc environments and contribute to growth of the continental crust. Thermomechanical models of arcs suggest that intermittent intrusion of magma batches leads to magma hybridization, remelting, and remobilization of earlier intrusive rocks. Here, we investigate the evolution of magmatic rocks of St. Peter Suite,South Australia, a typical calcalkaline arc suite. Magmatic rocks recording multiple intrusions and multiple magma interactions have undergone insitu remelting and remobilization forming migmatites. LA-ICP-MS U-Pb zircon dating yielded crystallization ages of 1647 ? 12 Ma for a tonalitic gneiss representing the oldest intrusive suite, and 1604 ? 12 Ma for a leucogranite representing the youngestintrusive suite. The rock suites record two deformation events associated with anatexis. The first event, was responsible for a dominant approximately E-W?striking foliation parallel to magmatic foliation, and associated with a dominantl
