摘　　要：贵州省册亨县沙子井金矿属微细粒浸染型金矿,矿体受构造和岩性的双重控制,主矿体产于夜郎组碎屑岩地层中的节理密集带和F11断裂破碎带中。区内夜郎组地层厚度20 m^60m,厚度较小,难以形成较大规模的矿体。F11断层在深部进入吴家坪组碳酸盐岩地层,后转化为层间断层继而消失,吴家坪组及其下伏茅口组地层均以碳酸盐岩为主,缺乏隔挡层,其岩性组合不利于成矿,综合分析沙子井金矿浅部找矿远景较小。The Guizhou province Ceheng County wells sand gold deposit is a micro fine disseminated gold deposit, the ore bodies are both controlled by lithology and structure, the main ore produced in the clastic rock formation of the Yelang concentratedjoint band and Fll fracture zone. A small area of Yelang formation thickness of 20 m 60m, the thickness of ore body is difficult to form large scale. The Fll fault in the deep into the group of carbonate formation Wujiaping, transformed into interlayer faults and then disappear, Wujiaping formation and its underlying Maokou Formation are dominated by carbonate, lack of barrier layer, the lithology combination is not conducive to a comprehensive analysis of gold mineralization, sand wells shallow prospecting small landscape.
