商县玉石坡大型萤石矿床的普查勘探工作,曾经以它的快速和较高质量荣获陕西省科学大会奖。该矿床严格受构造断裂的控制,但矿区构造特征及其组合规律的研究程度尚感不足。为了弥补这一缺点,本文对控制该矿床的构造型式试作探讨。笔者在本矿区曾做过一些工作,但因时间较短,收集资料欠丰,认识水平亦有限,谬误之处请指正。一、矿床地质简况矿区位于秦岭东西纬向构造带南亚带,侏罗纪九华山花岗岩体的东南部。矿区岩浆岩以斑状角闪黑云二长花岗岩为主,其次还有花岗斑岩脉、石英脉和煌斑岩
Shang County Shangbabu large fluorite deposit census of exploration work, once its fast and high quality won the Shaanxi Provincial Science Conference Award. The deposit is strictly controlled by tectonic faults, but the degree of research on the tectonic features and the combination rules of the mines is not enough. In order to make up for this shortcoming, this paper discusses the control of the structural type of the deposit. I have done some work in this mining area, but because of the short time, the collection of information is poor, the level of knowledge is limited, correct the mistakes please correct me. First, the geology of the deposit The mine is located in the south-west belt of the east-west latitudinal tectonic belt of the Qinling Mountains and southeast of the Jiuhuashan granite body of the Jurassic. The magmatic rocks in the mining area are dominated by porphyritic hornblende biotite monzogranite, followed by granite porphyry veins, quartz veins and lamprophyre
