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

Symington, Neil J.; Weinberg, R; Hasalova, Pavlina; Wolfram, Lauren C.; Raveggi, Massimo; Armstrong, Richard

Description

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 driven by fluctuations in temperature and water fluxing. While there are numerous examples in the literature of multiple intrusions and magma hybridization, field examples of remelting and remobilization of...[Show more]
