辽宁沔阳北沟矿区矿床地质特征及找矿标志

Geological Characteristics and Prospecting Indicator of Deposits in Mianyang Beigou Mining Area,Liaoning Province

沔阳北沟矿区位于华北地台中朝准地台北缘,岩浆活动强烈,地质构造复杂,成矿地质条件优越。通过对沔阳北沟矿区的地质背景、矿床地质特征及矿体地质特征的研究,同时深入分析了矿体特征、矿物组构特征、蚀变特征、土壤地球化学特征等,讨论了矿床成因,总结了找矿标志,为下一步找矿工作提供了指导意义。

Mianyang Beigou mining area is located in the northern margin of Sino-Korean paraplatform in North China platform,with strong magmatic activity,complex geological structure and favorable metallogenic geological conditions.Based on the study of the geological background,geological characteristics of the deposit and geological characteristics of the ore body in Mianyang Beigou mining area,the ore body characteristics,mineral fabric characteristics,alteration characteristics,soil geochemical characteristics,etc.are deeply analyzed,the genesis of the deposit is discussed,and the prospecting indicators are summarized,which provides a guiding significance for the next prospecting work.
