| 摘 要： | 经详细填图，将白马尖复式杂岩体解体出９１个侵入体，归并６个单元，３个超单元，它们均属燕山期产物，物源于壳幔混合岩浆。岩石由花岗闪长岩二长花岗岩钾长花岗岩方向演化，岩浆活动由弱强弱，一幕一幕向上推进，呈向北东迁移趋势。区域构造活动和岩浆自身演化的双重因素制约了白马尖超单元组合。

| Abstract: | Studies on the geologial and geochemical characteristics of the Huashugou (iron) copper deposit indicate that,following the developmint of the arc trough-basin system near the old continental margin, the Proterozoic volcanic and Sedimentary basement rocks were subjected to the interaction of the deep-circulating hydrothermal system ,the ore-forming material was leached,transported and finally exhaled into the seafloor to form the copper-bearing formations, the late metamorphisms made the ore -forming material be activated, transferred and enriched.The Huashugou deposit is an exhalation-sedimention-metamorphic (iron) copper deposit. |
