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 tuf-faceous siltstone, 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.
