Abstract:

Weijiayu gold deposit is located in the northeast plunging crown of Fuping mantle branch structure,its orebody is produced along the diabasic dike and surrounding rock broken contact zone and the deposit is a medium-low temperature nervation altered rock type gold deposit.Based on regional geological features,this article uses the theory of mantle branch structure,focus on analysis of its rock and hours controlling function,and hold that during the Fuping mantle branch structure activity in Yanshanian stage,NNE fault belts of Shanghuangqi-Wulonggou deep fracture and Zijinguan-Lingshan fracture leading of magma and ore hydrothermal.The intrusion of Luotuoan granite strain in this area is further communicated with the ore source at the depth,post-ore bearing hydrothermal solution ransports from bottom to top along the unsubstantial tectonic belt between early NW-diabase and surrounding rock,concentrated mineralization on the top and bottom near the diabase dykes.

Key words: mantle branch structure, geological characteristics, the ore source at the depth, Weijiayu gold deposit, Northern Taihang Mountains
