Porphyry Cu-Mo deposits and geodynamic settings, Siberia, Mongolia

摘要

The Siberian and Mongolian porphyry Cu-Mo deposits are confined to early Paleozoic, late Paleozoic and Mesozoic magmatic belts including magmatic complexes of various geodynamic settings (of subduction, collision and rifting nature). According to geological and isotopic data, ore-bearing porphyries were formed during rifting, but inherited petrogeochemical features of the preceding collision and subduction magmatism to a certain extent. The Siberian and Mongolian porphyry Cu-Mo deposits seem to be related to long-lived magmatic super-systems which were active in different geodynamic environments (from subduction and collision to rifting).
