辽宁龙潭沟地区地质特征及找矿认识

Geological Characteristics and Prospecting Cognition of Longtangou area in Liaoning Province

通过对龙潭沟地区开展地质测量、地球化学土壤测量和物探激电剖面测量等工作,总结了龙潭沟地区地层、岩性、构造、矿化及围岩蚀变等地质特征。研究结果表明Au、W元素是本区主要成矿元素,As、Cu等金属元素为成矿伴生元素。Au元素异常在本区具有规模大、强度高等特点,Cu、W元素在本区含量相对较高,可作为找矿指示元素。物探高阻异常多由闪长岩脉、石英岩脉所引起,或由闪长岩局部被石英岩脉充填所引起。根据本区地球化学、地球物理异常特征,认为本区具有较好的找矿前景,并指出了下一步找矿方向。

Through geological surveys,geochemical soil surveys,and geophysical IP profile surveys in the Longtangou area,the geological characteristics of the Longtangou area,such as stratigraphy,lithology,structure,mineralization,and wall rock alteration,have been summarized.The research results show that Au and W are the main metallogenic elements in this area,and metal elements such as As and Cu are associated elements of metallogenesis.Au anomaly has the characteristics of large scale and high strength in this area.Cu and W elements concentrate relatively high in this area,and can be used as ore-prospecting indicator elements.High resistance anomalies in geophysical prospecting are mostly caused by diorite veins and quartzite veins,or quartzite veins partially filling in diorite veins.According to the geochemical and geophysical anomaly characteristics in this area,it is believed that good prospecting result can be envisioned in this area,and the future prospecting direction is pointed out.
