摘要
近年在河北太行山地区找金,获突破性进展.作者综合了有关资料,肯定该地区金矿属中偏高温热液叠生矿床;岩浆活动为矿层中Au的活化迁移提供了热力源;一定的围岩蚀变是找矿的重要标志;区域变质和混合岩化导致微量而分散的Au的富集.
Based upon related geological data and file records, it is firmly believed by the author that gold deposits in Taihang Shan district, Hebei Province belong to mesothermal-hypothermal telescoped type. Heat source for the activation and migration of the gold in ore beds was provided by magmatic activity. Certain wallrock alterations are the important exploration guides. The concentration of dispersed gold in trace amount was resulted from regional metamorphism and migmatization.
