浅覆盖区萤石矿综合勘查方法研究——以内蒙古林西赛波萝沟门萤石矿为例

Comprehensive exploration method for fluorite deposits in grasslands covered area:A case study of the Saiboluogoumen fluorite deposit in Linxi,Inner Mongolia,China

随着萤石矿露头矿和浅部矿的逐渐减少,传统单一的方法已难以满足勘探需求。以内蒙古林西赛波萝沟门萤石矿为例,探讨了甚低频电磁法和便携式X射线荧光光谱分析方法在浅覆盖区萤石矿勘查中的应用效果,结果表明甚低频电磁测量可显示构造破碎带在平面上的展布情况,而便携式X射线荧光光谱分析可以显示元素异常的分布,判析构造破碎带的含矿性,在一定程度上弥补了单一地球物理方法存在的多解性问题。

With the gradually reducing of outcropped and shallow-seated fluorite deposits,the single and traditional method can not meet the needs of the exploration.Taking the Saiboluogoumen fluorite deposit in Linxi,Inner Mongolia for example,this paper studies the application effects of the very low frequency electromagnetic method （VLF-EM） and the portable X-ray fluorescence spectrometry （PXRF） in exploring fluorite deposits of grasslands.The results show that VLF-EM can define the distribution of structure fractures and the PXRF can define the distribution of element anomalies.The definition of element anomalies can distinguish the mineralization of the structure fractures so that to make up the ambiguous interpretation of a single geophysical method.
