浅析化探方法在武威市大口子萤石找矿中的应用

Application of Geochemical Exploration Method in Dakouzi Fluorite Mine in Wuwei City

通过对武威市大口子地区地表以下0.3~0.5m使用水系沉积物测量方法,圈定的氟元素异常与萤石矿体分布进行研究,发现该区氟元素异常与萤石矿体分布密切相关。对圈定的异常区采用岩石化学剖面、地质测量、探槽工程等进行异常查证,新发现萤石矿体2处,取得了较好的找矿效果。

By using the aqueous sediment measurement method 0.3~0.5m below the surface in the Dakouzi area of Wuwei city,the fluorine anomaly and fluorite ore body distribution were studied,and it was found that the fluorine anomaly in this area was closely related to the distribution of fluorite ore body.The delineated abnormal areas were verified by petrochemical profile,geological survey and exploratory trough engineering,and two new fluorite ore bodies were discovered,and better prospecting results have been achieved.
