摘要
陕西简池镇地区位于扬子板块北缘南江前陆—上叠盆地,为了明确找矿潜力,在研究区开展1∶2.5万水系沉积物测量。根据与成矿密切相关的K_(2)O、Na_(2)O、CaO、MgO、Cl、S、B、Rb、Cs、Li、Br、I等12种元素测试结果,分析了元素地球化学特征,确定研究区内Li为主成矿元素,Li-B-Rb-Cs-K_(2)O是寻找锂矿的指示元素组合,Li空间分布规律符合各地质体展布形态。结合成矿地质背景,圈定综合异常18个,通过异常检查工作,发现了多条锂矿(化)体,表明该地区具备了良好的成矿地质—地球化学条件,具有巨大的找矿潜力。
Jianchi Town of Shaanxi Province is located in the Nanjiang foreland-superimposed basin on the northern margin of the Yangtze Plate.To determine the prospecting potential,this study conducted a 1∶25,000 stream sediment survey in the study area.Based on the testing results of 12 elements and compounds closely related to mineralization,namely K_(2)O,Na_(2)O,CaO,MgO,Cl,S,B,Rb,Cs,Li,Br,and I,this study analyzed the geochemical characteristics of these elements and compounds and determined that Li is the major metallogenic element,Li-B-Rb-Cs-K_(2)O is the indicator element association for the prospecting of lithium deposits,and the spatial morphology of Li agrees with that of various geological bodies.By combining the metallogenic geological setting,this study delineated 18 integrated anomalies.Through the follow-up examination of the anomalies,multiple lithium ore bodies(mineralized points)were discovered,indicating that the study area has favorable metallogenic geological and geochemical conditions and great prospecting potential.
