拐河萤石矿区长约13公里,宽约4公里。地表出露矿点数十处,多为群众挖采,历时十年之久,年采精矿近万吨。目前正在兴建日处理百吨选矿厂,以充分利用中~低品位矿石。矿区地质概况该区位于伏牛山复背斜东端北翼,属“华熊沉降带”的一部分。区域地质构造复杂。地层变质作用强烈,岩浆活动频繁。根据卫星照片(ERTS—E_21/50万及1/100万)分析,该区所在为一小型山字型构造(面积达3800公里~2)。脊柱位于四里店~车路口一带,本区则位于脊柱与前弧接触部位。矿区出露地层主要是震旦系(Z)中、
River Kwai fluorite mining area about 13 km, 4 km wide. Surface exposed mine dozens of points, mostly for the masses to dig mining, which lasted for ten years, mining nearly 10,000 tons of concentrate. At present, a one hundred ton ore dressing plant is being constructed on a daily basis to make full use of mid- to low-grade ore. Geological Survey of the Mining Area The area is located in the north wing of the eastern end of the Funiu Mountain anticline, and is part of the “Hua Bear Subsidence Belt.” Regional geological structure is complex. Strong strata metamorphism, magmatic activity is frequent. According to satellite photos (ERTS-E 21/500000 and 1/1000000), the area is located in a small mountain font structure (3800km ~ 2 area). Spine is located in the Sili shop ~ car junction area, the area is located in the spine and forearc contact parts. The exposed strata in the mining area are mainly Sinian (Z)
