土壤地球化学测量工作对发现土壤中与成矿有关的地球化学异常进而对指导找矿具有重要的意义.内蒙古白音诺尔铅锌矿床是我国北方一个典型的矽卡岩型矿床,具有大而富的特点.选取内蒙古白音诺尔铅锌矿区某已开采矿体上方6号土壤垂直剖面、以及距离6号剖面分别约1.0km和4.5km的非矿土壤垂直剖面3和8,垂向上通过每隔10cm取样,进行了系统的土壤磁化率测试和与成矿有关的部分微量元素的总量测试分析.结果显示,尽管近矿剖面6和远矿剖面3中磁化率与土壤深度之间呈良好的负相关关系,但剖面6中9种元素含量均显示“顶底低中间高”的“倒C型”分布,而远矿剖面3和8中元素含量多呈动荡波动.这些研究思路与结论可为覆盖区表生土壤地球化学测量及矿产预测研究提供借鉴,对系统模拟和研究地球化学组分在矿区及周边残积土剖面中的迁移演化规律及其影响因素亦具有指示意义.
Geochemical measurements of soil geochemical anomalies associated with mineralization found in the soil and thus is of great significance for the direction of ore prospecting. Inner Mongolia Baiyinuoer lead-zinc deposit is a typical skarn type deposit in northern China, with large and rich .Selecting the vertical section of the soil above No.6 in a developed ore body of Baiyinnuoer lead-zinc mine in Inner Mongolia and vertical sections 3 and 8 of non-ore-bearing soil about 1.0km and 4.5km away from section 6 respectively, 10cm sampling, the soil magnetic susceptibility of the system test and the total amount of some trace elements related to metallogenic test were analyzed.The results show that, although the magnetic susceptibility between the near-ore section 6 and the remote ore section 3 and soil depth is good However, the content of 9 elements in section 6 showed “inverted C ” distribution of “top and bottom low middle high ”, while the content of elements in remote ore sections 3 and 8 mostly fluctuated. The ideas and conclusions can provide reference for the study of surface geochemical measurement of soils and prediction of mineral resources in the area covered by the system and to study the evolution and influence of the migration and evolution of geochemical components in the residual soil profile in the mining area and the surrounding area Indicative significance.
