| 摘 要： | 区域地球化学研究对于区域地质矿产预测具有重要指导意义。以内蒙古温根地区水系沉积物地球化学特征为研究对象, 将研究区元素的富集共生规律、组合异常特征、矿致异常解释和区域地质、构造、矿化作用有机结合, 总结研究区内地球化学异常对矿化的指示作用, 揭示温根地区可能的成矿元素和矿致异常特征, 进而为查明温根地区的成矿有利地段提供预测依据。研究结果显示, 区内Cu、Mo、Au具有较大成矿潜力。基于异常解释和排序结果, 优选出有色金属找矿远景区3处。

| Abstract: | Regional geochemical research has important guiding significance for the prediction of regional geology and mineral resources. Taking the stream sediment survey data of Wengen area in Inner Mongolia as the research object, the authors integrated the laws of enrichment and symbiosis, assemblage anomalies and ore-induced anomaly interpretation with the structure, mineralization and regional geology of the area, and summarized the indicating function of the geochemical anomalies, so as to reveal the potential ore-forming elements and the characteristics of anomalies, and then provide basis for identifying the favorable mineralization areas in the study area. Research results show that Cu, Mo, Au have great metallogenic potentialin the area. Based on the interpretation and ranking results of the anomalies related to mineralization, three nonferrous metalsore prospecting targets were optimally delineated. |
