苏州清明山石英砂岩矿自50年代建矿开采以来,生产规模不断扩大,目前年产矿石已超过10万吨。是华东地区的一个重要硅质原料基地。一、矿区地质概况矿区位于下杨子凹陷的苏州——湖州断块上,处于木渎短轴向斜南西翼。由于受后期岩浆活动破坏,北东翼为燕山期花岗岩大面积分布。整个矿区为—单斜构造。倾角15°～40°,展伸方向与山的走向基本一致。东西二侧断裂构造比较发育;燕山期晚侏罗世安山玢岩细脉及后期正长斑岩脉沿断裂侵入。地表山麓局部地段产生岩层滑动破碎。
Since its establishment in the 1950s, the quartz sandstone mine at Qingming Mountain in Suzhou has been expanding its production scale and currently has an annual output of more than 100,000 tons of ore. East China is an important base of silicon raw materials. I. Geological Overview of the Mining Area The mining area is located on the Suzhou-Huzhou fault block in the lower Yangzi Depression and lies on the southwestern wing of the short axis of Mudu. As a result of the late magmatic activity destroyed, the North East Yanshanian granite area distribution. The entire mining area is a monoclinic structure. Inclination 15 ° ~ 40 °, stretching direction and the trend of the mountain basically the same. The faults on both sides of the east and west developed relatively well. Late Late Jurassic andesite and vein facies faults intruded along the faults. Surface foothills in the local area of the rock slide broken.
