摘要
在广西苍梧县社垌矿区,利用磁测解译分析研究多金属矿体的空间展布特征,结合区域地质构造特征、地球化学特征及重力特征等综合成果,所获得的结果相互验证,从地表到深部立体勘查逐步深入,避免了单一方法的片面性和物探多解性,利用重力异常圈定岩体范围,利用磁异常确定接触蚀变带的位置,结合激电异常确定找矿靶区。有效降低了多金属矿资源勘查风险,在苍梧社垌地区取得了较好的找矿效果。
In Shedong mining area,Cangwu County,Guangxi,the spatial distribution characteristics of polymetallic orebodies are studied by the magnetic interpretation and analysis.Combined with the comprehensive result of regional and geological structure,geochemical and gravity characteristics,the exploration results are verified with each other,and the three-dimensional exploration is gradually deepened from the surface to the deep,avoiding the unilateral of a single method and the ambiguity of geophysical exploration method.The gravity anomaly is used to delineate the range of the rock mass,the magnetic anomaly is used to determine the location of the contact alteration zone,and the prospecting target area is determined by the induced polarization anomaly.The exploration risk of polymetallic mineral resources is effectively reduced,and a good prospecting effect has been achieved in Shedong area,Cangwu County.
