摘要
杜荒岭金矿赋存于燕山晚期的石英闪长(斑)岩中,严格受近EW向断裂构造带控制。主要蚀变类型有硅化、绢云母化、绿泥石化、黄铁矿化、褐铁矿化、高岭土化和碳酸盐化等。蚀变演化可划分为早成矿期、中成矿期和晚成矿期蚀变。金矿化与蚀变关系密切,尤其与硅化、黄铁矿化和绢英岩化最为密切,为典型的破碎蚀变岩型金矿。总结了本区找矿标志及矿床成因,认为杜荒岭金矿属中低温热液蚀变岩型金矿床。
Duhuangling gold deposit occurred in the quartz diorite of Late Yanshan Epoch.The ore-bodies are directly controlled by EW-trending fault structure zone.The main types of the wall-rock alteration include quartzitification,sericitization,chloritization,pyritization,limonitization,kaoliniti-zation,carbonatization.Evolution of the alteration may been divided into tree atages,namely,early-mineralizing alteration,middle-mineralizing alteration and late-mineralizing alteration.The gold min-eralization is closely reated to the alteration,especially to the quartaitification,pyritization and sericit-ization-quartzitification.This is a typical fractured alteration type gold deposits.This is a meso-epi-thermal alteration type gold deposit which related with subvolcanic rock of Late Yanshan Epoch,Based on the prospecting criteria in the area.
