内蒙古奇安绰罗地区地层含矿性研究

Discussion on ore-bearing features of the strata in the Qi'anchuoluo area,Inner Mongolia

地球化学研究的中心任务是研究地层及各类岩石中成矿元素的分散富集规律。以内蒙古奇安绰罗地区地层的岩石、岩屑样品化学元素光谱分析数据为基础,对测区各地层进行比较系统的地球化学分析,讨论了各地层中Au、Ag、Pb、Mo、W、Cu、Zn、As、Sb、Bi、Hg、Sn 12个成矿元素的地球化学特征,从成矿元素的相对富集与贫化、变化性、后期作用叠加强度几个方面考察地层中成矿元素的成矿潜力,揭示研究区主要矿产的赋矿层位。

This study performed systematical geochemical analysis of the strata in the Qi＇anchuoluo area of Inner Mongolia based on the test results of trace elements in rocks and soil specimens, and then discussed the geochemical characteristics of ore-hosting elements including Au, Ag, Pb, Mo, W, Cu, Zn, As, Sb, Bi, Hg and Sn in each strata. We also analyzed the metallogenic potentials of the ore-forming elements from the aspects of relative enrichment or depletion, variations, overlapping intensity during post-sedimentary processes to reveal the main ore-hosting strata in the study area.
