摘要
The copper-molybdenum deposits in Daxinganling region are related to the Paleozoic and Mesozoic hypabyssal intrusive and volcanic-subvolcanic rocks. Those deposits were formed in the epicontinental magmatic zones, orogenic belts and deep-fracture zones, during Caledonian, Variscan and Yanshanian epochs. The wall rocks consist of granodiorite, granodioritic porphyrite, adamellite, andesite, dacite, rhyolite, andesitic porphyrite, rhyolitic porphyry and pyroclastic rocks, with alterations of silicification, sericitization, K-feldspathization, hydromicazation, illitization, chloritization and carbonation.
