| 中文摘要: |
| 萨茹塔拉是内蒙古中部近年来发现的具有较好找矿潜力的钼-铜-金矿化区。文章在1：5 万水系沉积物测量的基础上，结合区域地质背景特征，从单元素异常、异常元素组合特征等方面对该地区已发现的多处金、钼等矿床、矿点进行初步分析，结果表明已知矿床大部分位于矿致异常浓集中心，多元素组合异常套合较好，并指示了多处同样具有找矿前景的异常浓集中心。二叠系是赋矿有利层位；频繁的岩浆活动不但提供了成矿物质，而且使地层中的成矿元素进一步富集，并在构造有利部位成矿。 |
| 英文摘要: |
| Sarutala area is a potential Mo-Cu-Au prospecting area discovered in recent years. Based on results of river sediment survey at scale 1：50 000, regional geological background, characteristics of single element anomly and characteristics of the anomly element combination this paper analyzes several Au, Mo deposits and occurrences located before. The analysis shows that the deposits and occurrences occur at concentration center of the elements and different element anomlies are well overprinted. The other concentration centers without prospecting workings should be potential for further prospecting. Permian strata are the ore-hosting strata. Repeated magmatism not only provides ore materials but also makes further enrichment of ore elements from the Permian strata and the ore deposit may be formed at favorable tectonic position. |
