河北崇礼东坪金矿3号脉矿床地质特征及成因研究

Geological characteristics and genesis of the No. 3 vein deposit in Dongping gold deposit, Chongli, Hebei

东坪金矿3号脉大地构造位置上位于中朝板块和西伯利亚板块构造交接带。区内构造岩浆岩发育。与成矿密切相关的为水泉沟杂岩体,矿体产于水泉沟偏碱性杂岩体南侧内接触带,赋存于构造蚀变岩中。矿床成因类型为同熔—重熔高中温热液充填交代石英脉—蚀变岩型金矿床。

The geotectonic position of vein No. 3 in Dongping gold mine is located in the Sino French plate and Siberia plate tectonic transfer zone. The tectono magmatic rocks are developed in the region. Closely related to mineralization is the Shui Quan Gou complex, which occurs in the inner contact zone on the south side of the Shui Quan Gou alkaline complex and occurs in the altered rocks. The genetic type of deposit is synmelting remelting high temperature hydrothermal filling metasomatic quartz vein altered rock type gold deposit.
