摘要
金星头杂岩体为燕山晚期侵入的中酸性浅成—超浅成岩类 ,为同源岩浆多次脉动侵入的产物。其中清明沟辉石角闪闪长玢岩单元与金矿化关系密切 ,金矿 (化 )体均产于该岩体与白云质灰岩、钙质页岩的接触带上。
Jinxingtou complex which belongs to intermediate rock shallow-hypabyssal or super-hypabyssal rocks intruded in late Yanshan period is mainly composed of pyroxene-diorite, amphibolite-diorite porphyrite and quartz-diorite-porphyrite. It is the product of comagmatic multi-impulses. Pyroxene-amphibolite-diorite-porphyrite has a close relation with the gold deposit, and gold bodies occurred in the contact zone between the complex and Zhushadong formation or Mantou formation. The deposit belongs to scarns-type gold deposits.
