青海赛多浦岗日地区水系沉积物地球化学特征及成矿预测

Geochemical characteristics and metallogenic prediction of stream sediments in Saiduopugangri,Qinghai Province

通过对赛多浦岗日地区1∶50000水系沉积物测量元素含量分布、富集离散及组合特征的分析,讨论了各元素之间的组合关系以及与地质背景的关系,对该区主要成矿元素及成矿规律有了进一步认识;结合地球化学异常及地质背景,初步划分了2个成矿远景区,指出在楚多曲地区寻找铅锌多金属矿的潜力巨大,景日强玛地区具备铅银多金属矿床的潜力,为该区成矿预测及下一步地质找矿工作部署提供依据。

Through the analysis of element content distribution,enrichment dispersion and combination characteristics of 1 ∶50000 water sediments in Saiduoganggang area,the relationship between each element and the relationship with geological background was discussed. The main mineralization in this area and metallogenic regularity have been further understood,combined with geochemical anomalies and geological background,two ore-forming prospects have been preliminarily divided,indicating that the potential for finding lead-zinc polymetallic ore in the Chuduqu area is huge,and the Jingri Qianma area has the potential of lead-silver polymetallic deposits provides a basis for metallogenic predictions in the area and the next step in geologic prospecting.
