摘要
Based on the analysis of the geological background,distribution of orebodies,characteristics of ore and altered minerals,it is concluded that the Siheshun pyrite deposit belongs to meso-hydrothermal filling and metasomatic type.The main ore-controlling and ore-forming structures are the east-west-trending faults,which are also the direction for regional prospecting.The altered mineral assemblage of silicification,sericitization and chloritization is the major indictor for ore-searching.With geophysical and geochemical anomalous features,the exploring direction is point out to achieve the prospecting breakthrough in the deep and peripheral areas.
