| 中文摘要: |
| 内蒙古毛盖吐锡铅锌矿位于黄岗梁-甘珠尔庙锡铜铅锌银多金属成矿带的中南段,属于半干旱草原荒漠景观区。该文通过1∶10000土壤地球化学测量,运用元素异常组合和元素分异富集规律等分析方法,发现矿区内Sn、Cu、Pb、Bi、Mo、Zn、W等元素异常发育,并圈定8处综合异常,明确Sn、Cu、Pb、Bi、Mo、Zn、W为毛盖吐地区主成矿元素。结合研究区构造分析,发现北东向构造对元素富集成矿有明显的控制作用。本次研究结果表明土壤地球化学测量在该半干旱景观地区对揭示元素异常及找矿工作具有实用性及可靠性。 |
| 英文摘要: |
| Maogaitu Sn-polymetallic deposit, Inner Mongolia, is located in the middle-south section of Huanggangliang-Ganzhuermiao Sn-Cu-Pb-Zn-Ag metallogenic belt, belonging to semi-arid grassland desert landscape area. In this contribution, through 1∶10000 soil geochemical survey, using the analysis methods of element anomaly combination and element differentiation and enrichment regularity, which show that elements such as Sn, Cu, Pb, Bi, Mo, Zn and W are abnormally developed in the mining area, and eight comprehensive anomalies are delineated, and it is clear that Sn, Cu, Pb, Bi, Mo, Zn and W are the main metallogenic elements in Maogaitu area. Combined with the structural analysis of the study area, it is found that the NE-trending structure has obvious control over the enrichment and mineralization of elements. The results of this study show that soil geochemical survey is practical and reliable for revealing element anomalies and prospecting in this semi-arid landscape area. |
