辽宁洼塘地区土壤地球化学特征及找矿意义

Soil geochemical characteristics and prospecting significance in the Watang area,Liaoning

  • 摘要: 洼塘地区位于辽东裂谷东段,区域内已发现多处矿床(点),成矿地质条件优越。在1∶1万土壤地球化学测量的基础上,分析了洼塘地区地球化学特征,对元素变异系数、单元素异常特征及异常组合特征进行地球化学统计分析,论述了7种元素的成矿潜力,发现Ag、Pb元素具有较好的成矿潜力。根据地质条件及元素异常特征,圈定了综合异常2处,对Ⅰ号综合异常进行槽探工程验证,发现2条矿(化)体,为进一步地质勘查工作提供了依据。

     

    Abstract: The Watang area is located in the east part of the rift in eastern Liaoning,where many deposits(spots) have been found and the metallogenic conditions are favorable.The geochemical characteristics of Watang area were analyzed on the basis of 1∶10 000 soil geochemistry survey.The paper studied the geochemical characteristics,analyzed statistically the element variation coefficients,the single element anomaly and the combined element anomaly,and discussed the metallogenetic potentials of 7 elements,finding that Ag and Pb have great potentials.According to the geological conditions and the element anomaly characteristics,2 comprehensive anomalies are delineated.Trenching verification in the Ⅰ anomaly revealed 2  ore(mineralized) bodies,which could provide scientific evidence for nextstep geological exploration work.
