Geological feature of the Donggou gold deposit in Shanxi province
摘要
Abstract
Donggou area in Xiaxian County,Shanxi province,is located in the south of contact zone between the Erdos massif and Hehuai massif in the North China plate, in the middle of Zhongtiao Mountain uplift in Taihang Mountain area. With complete stratum exposed and strong magmatic activities, the metallogenic condition is very superior. We, No.214 geological team of Geological Survey of Shanxi Province, worked on it from 2012 to 2015. To narrow the range of prospecting, we conducted a 1/10 000 geological mapping and the soil geochemistry survey. Through the analysis of metallogenic condition in Aigou area, we considered tectonic fracture zone and the secondary tectonic fracture zone have an important significance in mineralization. We anatomized the fracture zone and the abnormal key parts by trenching, drilling and found the following ore bodies: thirteen gold ore bodies, one copper ore body and one gold ore body in low quality. Gold ore bodies are discovered in diabase vein and contact zone of the surrounding rock. So, we inferred the mineralization refers to the incursion of diabase vein and the contact zone. The cause is about the deposit with low temperature in fracture zone. We can prospect better with the basis and suggestion by the analysis of geological features and geochemical anomalies.关键词
