摘要
1∶5万水系沉积物测量作为一种重要的地球化学普查手段,现已被广泛应用.此次在三道砬子—错草顶子地区开展1∶5万水系沉积物测量,旨在圈定异常,通过对异常的检查和评价,圈定找矿靶区,进而划分找矿远景区,并作出成矿预测.基于该区水系沉积物测量的11种元素原始测量数据,统计分析了水系沉积物元素分布与特征参数,总结了富集离散规律、元素组合特征及其与成矿地质条件的关系.结合成矿地质条件、地球化学特征,圈定出综合异常24处,在综合研究的基础上划分出了 3处找矿远景区,具有较大的成矿潜力,为多种有色金属矿产靶区优选、资源潜力评价和下一步地质找矿工作指明了方向.
Abstract
As an important means of geochemical survey,the 1∶50 000 stream sediment survey has been widely used.The 1∶50 000 stream sediment survey is carried out in the Sandaolazi-Cuocaodingzi area,aiming at delineate anomalies.Through the inspection and evaluation of anomalies,the prospecting target area is delineated,and then the prospecting area is further divided,and mineralization prediction is made.Based on the original measurement data of 11 elements measured of the stream sediment in the area,the distribution and characteristic parameters of elements in stream sediment are statisti-cally analyzed.The enrichment and dispersion rules,element combination characteristics and their relationship with metal-logenic geological conditions are summarized.Combined with the metallogenic geological conditions and geochemical char-acteristics,24 comprehensive anomalies have been delineated,3 prospecting areas have been divided,which have great mineralization potential.This has pointed out the direction for the optimization of various non-ferrous metal mineral target areas,resource potential evaluation,and the next geological prospecting work.
