| 摘 要： | 长江中下游地区矿产丰富,不少矿区为冲洪积物所覆盖。基于烃汞气体挥发性、穿透性强以及迁移距离远的特点,文章利用烃汞综合气体测量法针对冲洪积物覆盖的特殊景观区开展了探索性的找矿试验研究。通过对长江中下游地区烃汞背景值和不同矿床类型烃汞异常场的研究,以及典型矿床烃汞测量找矿的有效性试验,结合烃类组分微观结构对比分析等方面的研究,发现长江中下游地区大部分矿床在成矿过程中伴随形成烃类气体原生异常场,同时,地表冲洪积物中含有与深部矿床同源的烃类异常信息,初步显示了烃汞测量法在冲洪积物覆盖区应用于找矿是可行的。

| Abstract: | The region in middle and lower reaches of the Yangtze River is rich in minerals, and many mining areas in this region are covered by the alluvium. In consideration of the characteristics of hydrocarbon and mercury such as strong volatile, penetrability and faraway migration distance, the authors conducted an ore prospecting test research on the special landscape of alluvium cover area by using the integrated hydrocarbon and mercury method. In this paper, based on the study of the background of hydrocarbon and mercury and their primary anomaly halos in different types of deposits in middle and lower reaches of the Yangtze River, the effectiveness test of hydrocarbon and mercury method for ore-prospecting, and the contrastive analysis of the microstructures of hydrocarbon component, the authors revealed that primary anomaly halos of hydrocarbon and mercury were formed during mineralization in most deposits of this region. Meanwhile, the alluvial materials contain the anomaly information of hydrocarbon similar to the information in deep deposits. The results obtained by the authors preliminarily indicated that integrated hydrocarbon and mercury method is suitable for ore-prospecting in alluvium landscape. |
