山东邹城朝阳洞地区脉石英地质特征及成因浅析

Geological Characteristics and Genesis of Vein Quartz in Chaoyangdong Area,Zoucheng,Shandong Province

山东邹城朝阳洞地区脉石英主要赋存于新太古代晚期峄山序列及傲徕山序列侵入岩内。石英脉整体走向北西,与区内断裂构造方向大致相同,沿走向延伸10~846.40m,厚度0.5~12.0m。脉石英矿石主要为低温石英,矿石内包裹体以气液包裹体为主。矿床类型为岩浆期后热液型。发现规模较大的脉石英4处,区域找矿前景较好。

Vein quartz in the Chaoyangdong area of Zoucheng, Shandong province, is mainly deposited in the late Neoqua archean Yishan sequence and the Aolaishan sequence intruding into the rock. The overall direction of the quartz vein is NW, which is roughly the same as the direction of the fault structure in the region. It extends along the direction from 10m to 846.40m and has a thickness of 0.5m to 12.0m. Vein quartz ore is mainly low-temperature quartz, and the inclusions in the ore are mainly gas-liquid inclusions. The deposit type is hydrothermal after the magmatic period. 4 large-scale veined quartz were found, and the prospect of regional prospecting is better.
