Magmatic arcs related to the subduction of oceanic lithosphere are prospective for porphyry Cu±Mo±Au and epithermal Au deposits. Recently, porphyry and epithermal deposits that formed after subduction ceased have also been recognized in several parts of the world; these deposits may be generated during or after collisional processes. This research program aims to examine the tectonic and magmatic controls on porphyry and epithermal ore deposit formation that operate both during and after subduction.

与海洋岩石圈的俯冲有关的岩浆弧是斑岩铜±mo±au和表皮AU沉积物的前瞻性。最近，俯冲后形成的斑岩和表皮沉积物在世界几个地区也被认可。这些沉积物可以在碰撞过程中或之后产生。该研究计划旨在检查在俯冲过程中和之后运行的斑岩和表皮矿石沉积物形成的构造和岩浆控制。
