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 orebodies are directly controlled by EW-tronding fault structure zone. The main types of the wall-rock alteration include quartzitification, sericitization, chloritization, pyritization, limonitization, kaolinitization, 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 roared to the alteration, especially to the quartaitification, pyritization and sericitization-quartzitification. This is a typical fractured alteration type gold deposits. This is a meso-epithermal alteration type gold deposit which related with subvolcanic rock of Late Yanshan Epoch, Based on the prospecting criteria in the area.
