摘要
排山楼金矿发育有带状的蚀变晕。蚀变晕明显受韧性剪切带强带控制,从边部向中心根据蚀变强度不同可划分为:绿泥石化带,铁白云石化带和黄铁矿-绢云母化带。金矿化的程度与蚀变强弱关系密切,蚀变愈强金的品位愈高,因此,蚀变晕是寻找金矿的重要标志。
There are developed altercd halo zones obviously controlled by a strong zone of the ductile shear zone in Paishanlou gold deposit.lt can be divided into three altered zones from outside to inside,according to the strength of the alteration: planar chloritization, ferrodolomitization and pyrite-sericitization zones.The degree of the gold mineralization intergrowing with altered wallrocks are closely concerned with the intensity of alteration, the stronger alteration, the higher the tenor.So the altered halo is the most direct and favorable sign to search for gold deposits.
