摘　　要：忠宝钨矿床赋存于下泥盆统阿尔彼什麦布拉克组下亚组第二岩性段一套碎屑岩夹碳酸盐岩与华力西早期酸性侵入岩体的接触带附近,矿体主要产于内、外接触带的矽卡岩、云英岩化花岗岩中,有意义的矿化多产于复杂矽卡岩中。矿体受倾伏背斜构造和北东向的断裂带控制,具簇群丛生的特点,呈透镜状、似层状、脉状及不规则状。矿石中有用矿物主要为白钨矿,成矿作用具明显的多阶段性,矿床成因类型为矽卡岩型。Zhongbao Tungsten deposit is occurs in contact zones between a series of clastic rocks inter-bedded with carbonates that located upper 2nd lithological member of bottom sub--formation of Lwer Devonian Kangbutiebao Formation Team and early Variscian intrusive rocks.The Ore bodies are lay in skarn and greisenization granite inner and outer contact zones. The significative mineralization mostly occurs in complicatedness skarn.The Ore bodies are controlled by plunging anticline structure and fault zone of north-east.The ore bodies have characteristic of cluster and convergences, for example, lentoid,samdwich,nervation and anomalistic. The mostly available miniral is scheelite in ore.Ore forming action are distinct represent muhistage,The deposit forming type is skarn.
