摘要:
为展现综合物探方法在蚌埠隆起区金多金属矿勘查中的应用效果,更好地指导该区找矿工作,该文以怀远双沟勘查区为例,通过开展面积性高精度重磁测量和综合物探剖面测量,初步建立了近EW向与NE—近NS向叠加的构造格架,并经钻探验证发现了分别受韧脆性断裂和脆性断裂控制的2种类型的金多金属矿化带。在此基础上,总结了勘查区NE—近NS向的磁异常中心和重磁异常梯级带2种金多金属矿成矿有利部位,识别出NE—近NS向磁异常、NE—近NS向重磁异常梯级带、重力异常梯级带背景下的局部重力高、CSAMT剖面上的视电阻率等值线梯级带或明显的错断带等特征,作为区内金多金属矿的综合地球物理找矿标志。
Abstract:
In order to show the application effect of comprehensive geophysical survey in gold polymetallic ore exploration in Bengbu uplift area and better guide the prospecting work, this paper carried out areal high-precision gravity-magnetic survey and comprehensive geophysical profile survey in the Huaiyuan Shuanggou case study area, and then preliminarily built a superimposed structural framework of near EW and NE-near NS direction. Based on drilling verification, two types of gold polymetallic mineralization zones respectively controlled by ductile-brittle and brittle fractures are discovered. Accordingly, two kinds of gold polymetallic ore metallogenic favorable areas are concluded, namely the NE, near NS magnetic anomaly center, and the NE, near NS gravity-magnetic anomaly cascade zone. The NE, near NS magnetic anomaly, the NE, near NS gravity-magnetic anomaly cascade zone, local gravity height under the background of gravity anomaly cascade zone, and the apparent resistivity contour cascade zone or obvious fault zone on the CSAMT profile are recognized as the comprehensive geophysical prospecting indicators for the gold polymetallic ore in the region.
