ANALYSIS ON THE METALLOGENIC SYSTEM OF WENZHANGZI GOLD DEPOSIT IN WESTERN LIAONING PROVINCE

The Wenzhangzi gold deposit, occurring in the volcanic-sedimentary rocks of Jurassic Tiaojishan Formation and Mesozoic granodiorite, belongs to the mineralization type of altered rock. Study reveals that the gold-bearing formation of Mesozoic magmatic rocks, Late Indosinian-Yanshanian magmatic system and ductile-brittle fault system, as the major controlling factors for gold mineralization, are closely related with the metallogenesis in terms of space, time and materials. The mineralization types are depended on both tectonic stress field and the mechanical property of fractures.
