中文摘要: 内蒙古阿拉善塔布格地区主要地貌形态为荒漠、戈壁和山地,本文基于1:1万土壤地球化学测量工作成果,系统总结了塔布格地区地质特征,并对研究区内元素含量、异常组合和土壤地球化学异常等特征进行研究,结果表明:Au、Ag、Pb异常强度高、规模大,具有明显的浓集中心和浓度分带,多元素异常套合好,且与地质构造对应,异常查证发现含金石英脉,Au、Ag、Pb为主要成矿元素,As、Sb、Bi、Hg、Sn、Cu、Mo、Zn、W为成矿指示元素。综合地质成矿背景及化探异常特征,在区内圈定两处以金为主的多金属找矿靶区,认为后续工作主攻矿种应为金,主攻矿化类型为与韧-脆性构造变形有关的构造热液型金多金属矿化。
Abstract:Desert, gobi and mountain are the main topographic features of Tabuge area, Alixa right banner,Inner Mongolia. On the basis of soil geochemical survey at scale of 1:10000 in Tabuge area, the geological characteristics are summarized and characteristics like the elemental content, anomalous assemblage and soil geochemical anomaly are studied in this article. The results suggest that Au, Ag and Pb have high anomaly intensity, large scale, and obvious concentration center and concentration zone.The multi-element anomaly is well fitted, corresponds to geological structure, and the anomaly verification shows that there are gold-bearing quartz veins, with Au, Ag and Pb as the main ore-forming elements and As, Sb, Bi, Hg, Sn, Cu, Mo, Zn, W the ore-forming indicator elements. Considering the geological ore-forming background and characteristics of geochemical anomaly, two gold-based multi-metal prospecting target fields are set up in the area. It is believed that the main mineral to study should be gold, and the main mineralization type should be the gold polymetallic mineralization of structural hydrothermal type which is related to tough-brittle tectonic deformation.
