内蒙古撰山子金矿黄铁矿的热电性特征及其与金成矿作用的关系

PYROELECTRICITY OF PYRITE FROM THE ZHUANSHANZI GOLD DEPOSIT, INNER MONGOLIA AND ITS RELATIONSHIP WITH GOLD MINERALIZATION

研究了撰山子金矿床中金的主要载体矿物黄铁矿的形成世代、黄铁矿热电性的一般特征及黄铁矿的热电性与晶体形态、化学成分及金成矿作用的关系。结果表明 :与岩浆作用有关的金矿床中 ,黄铁矿的导电类型既有n型、p型 ,又有n p中间型 ,并以p型为主 ;不同成矿阶段的黄铁矿其热电性特征不同 ;黄铁矿热电性特征在矿体空间上具有一定的规律。

This paper discusses the generations of pyrite, the main mineral carrier of gold in the Zhuanshanzi gold deposit, the pyroelectricity of pyrite and the relation between pyrite pyroelectricity and crystal shape, the relation between pyrite pyroelectricity and chemical composition, and the relation between pyrite pyroelectricity and mineralization of gold. The research shows that: a) pyrite in the gold deposit related to magmatism is characterized by mixed-conductance;b)the pyrites formed in different mineralization stages have different features of conductance;c)the pyroelectricity of pyrite show a certain distributional law in orebody,which will guide ore-search and deep ore-prospecting in the future.
