Structure Evolution and Mineralization of Derbugan Metallogenic Belt in Northern China
中国北部得尔布干成矿带构造演化与成矿作用

Derbugan deep fracture controlled a magor zone of volcano intrusive processes and polymetal mineralization. The fracture zone has been activated for a long time from Caledonian to Tertiary period until modern time. The many stages tectono magmatic activities formed many intrusives with different epochs and scales, and large area Mesozoic volcanic rocks. We research over hundred ore deposits and/or mineraling spots in Derbugan metallogenic belt and find that deposit distribution has a close relationship with volcanic (intrusive) processes controlled by the structures. Go by studying, Derbugan fracture controlled regional structure, the secondary and studying various ore-controlled structures, this paper summarizes different scale ore-controlled structures in the metallogenic belt. It is important to guide prospecting deposits in this area in the future.
