摘要
小加山钼钨矿床成因类型为斑岩型矿床。矿床的赋矿地层和岩性为古生界泥盆系大南湖组凝灰质粉砂岩、凝灰岩及安山岩等;钨矿产于地表和浅部,钼矿完全隐伏于地下中深部,矿床总体赋存规律是上钨下钼,两者互为共生矿产且彼此不相连接;矿区年降水量极小而无地表水体;矿体及围岩大部属坚硬岩石;矿山外部环境对开采基本无影响。总之:矿山开发水工环诸多因素均属简单类型。
The genetic type of Xiaojiashan molybdenum tungsten deposit belongs to porphyry deposits, with tuffaceous sihstone, tuff and andesite, etc. in Dananhu Group Devonian system Palaeozoic era for its ore strata and li- thology; the tungsten ores are formed in the earth surface and shallow regions, while the molybdenum are complete- ly concealed deeply underground, and regularity of ore deposit is that tungsten always on the upper place of molyb- denum, they are paragenetic mineral but not connected to each other; there are seldom precipitation in the mining area or surface water; the wall rocks of the ore body are mainly hard rocks ; the external environment of the mine do not have any negative effects on mining. In a word： there are not so many hydrological or environmental problems for the mine development.
