摘要
阳山金矿带位于扬子板块、松潘-甘孜地块和南秦岭地块交接的文县弧形构造带内,矿体赋存于泥盆系中统三河口组浅变质碎屑岩建造中。矿床受地层、构造及岩浆活动共同控制,构造是最主要的控矿因素,控制了岩浆活动、成矿流体运移、矿体定位及形态产状和围岩蚀变的分布。
The Yangshan An ore zone lies in the Wenxian arcuate structural zone between the Songpan-Garz landmass and the south Qinling land mass. Au orebodies are confined to the epimetamorphic clastic rock of the Middle Devonian Sanhe Formation. Au deposits are controlled by stratigraphic horizon, magmatic rock and, especially, structure which brought magmatism, ore fluids migration, ore location, wall rock alteration and shape of orebodies under control.
