摘要
以江山—绍兴断裂带北东端桐树林~潘村韧性剪切带中的金矿特征为例,阐述韧性剪切带与金矿化的关系,认为该韧性剪切带对金矿的成矿和窑矿具明显的控制作用,剪切带与神功期石英闪长岩的接触部位是金矿分布的有利地段。剪切带内浅色蚀变带和糜棱岩带及成群出现的含碎裂状黄铁矿的石英脉是良好的找金标志。根据韧性剪切带具有长期多次活动、产状变化复杂的特点,今后应注意在剪切带深部寻找工业矿体。
Taking the gold deposits in Tongshulin - Panchun ductile shear zone(north - eastem part of Jiangshan- shaoxing faulted zone) as example, this paper expounded the relationship between ductile shear zone and gold mineralization, It is considered that ductile shear zone has obvious control on the mineralization and host of gold, and the contact part of ductile shear are and the quartz diorite of shengong Period is the favorable area for gold distribution. The light - colored alteration zone and mylonite zone in the shear zone, and the cataclastic pyrite bearing quartz vein occuring in groups are marks for gold prospecting. Ductile shear zone is characterized by long - period and multiple axtivities,various and complicated occurrences, So, attentions shoul be paid to the deep parts of shear zone for industrial ore body prospecting.
