沟系土壤地球化学测量在丹巴县永西金多金属矿区普查中的应用

Application of Trench Soil Geochemical Survey in the Census of Yongxi Gold Polymetallic Mining Area in Danba County

这是一篇地球科学领域的论文。本文通过在丹巴县永西金多金属矿普查矿区开展的1∶25000沟系土壤地球化学测量工作,揭示了该地区以金、银、砷、锑为代表的元素地球化学特征及异常分布规律,发现了一批有价值的地球化学综合异常,对地球化学异常区的找矿潜力进行分析,进一步缩小了找矿范围,圈定了1个找矿靶区,对该靶区实施工程验证,取得了较好的找矿效果,证明沟系土壤地球化学测量方法在本区的地质勘查工作中是有效的,为进一步的地质工作提供了科学依据。

This is an article in the field of earth sciences.Based on the 1∶25000 trench soil geochemical survey carried out in the Yongxi gold polymetallic mining area in Danba County,this paper reveals the element geochemical characteristics and anomaly distribution laws represented by gold,silver,arsenic and antimony in this area,finds a number of valuable geochemical comprehensive anomalies,analyzes the prospecting potential of geochemical anomaly areas,further narrows the prospecting scope,and delimits a prospecting target area.The engineering verification of the target area has achieved good prospecting results,which proves that the trench soil geochemical survey method is effective in the geological exploration work in this area,and provides a scientific basis for further geological work.
