Abstract
The geodynamic processes that control large-scale accumulations of ore are poorly understood. It has commonly been suggested that massive ore deposits are generated through a combination of factors in the Earth’s system. In the Lachlan Fold Belt of southeastern Australia, world-class orogenic gold and porphyry gold-copper deposits formed simultaneously at_~440 Ma in distinct tectonic settings. The driving mechanism that controlled the extraordinary temporal coincidence of these deposits remains largely unexplained. We propose that the interplay of a mega-subduction system and mantle processes could explain the generation of the giant_~440 Ma gold deposits and related metallogenic, tectonic, magmatic and sedimentary events elsewhere in Australia.
