摘    要:斑岩型金矿是云南重要的金矿类型。将与富碱斑岩有关的金矿床从斑岩类型角度划分为四种类型:与二长斑岩有关的构造破碎带蚀变岩型金矿床;与正长斑岩有关的岩体接触构造带脉状金矿床;与正长(粗面)斑岩有关的构造破碎带型金矿床;与花岗斑岩有关的石英-多金属硫化物金矿床。同时从不同类型斑岩、成矿构造和地球化学条件等多角度阐述了斑岩型金矿床形成的条件,认为本区斑岩型金矿床具有多类型、多成因与成矿作用多期次的特点。

关 键 词:金矿床  成矿地质特征  控矿条件  构造破碎带  地球化学  成矿构造  成矿作用

Abstract:Porphyry gold deposits are one of important type gold deposits in Yunnan. Based on the different porphyries, the gold deposits related with porphyry can be divided into four types: (1) the alteration rock type gold deposit related to ivernite in the structural fractured zone; (2) the vein type gold deposit related to orthophyre in the structural contact zone; (3) the structural fractured zone type gold deposit related to orthophyre; (4) the quartz-polymetal sulfide type gold deposit related to granite porphyry. It has been summarized systematically that forming conditions of porphyry type gold deposits have the characters of multiple types, multiple genesis and multiple mineralization.
Keywords:porphyry  gold deposit  western-northwestern Yunnan  ore-controlling condition
