| 摘 要： | 长安大型金矿床位于哀牢山成矿带南段,矿区内出露煌斑岩、辉长岩、辉绿岩、正长花岗岩、正长花岗斑岩等岩株和岩脉,矿体均与脉岩共生或相互切穿。各类岩浆岩和矿石的地质、岩相学、岩石地球化学的系统研究表明,矿区内岩浆岩可能为同源岩浆演化产物,但煌斑岩、辉绿岩与矿化关系更为密切。金成矿物质具有壳幔混源的特点,成矿流体由岩浆水与地层变质水混合而成。在喜山期,强烈的壳幔相互作用过程导致了区内的岩浆和热液活动,大规模富碱岩浆上侵的热驱使岩浆水循环并与矿区地层在造山作用下脱水产生的富CO2的变质水混合,萃取地层及略早形成的脉岩中的Au等成矿元素,在适宜的物理化学条件下和成矿空间内卸载并富集成矿。
