摘　　要：该研究以区内已知矿化点为基础,以磁法地球物理勘查为工作手段,通过1∶1万磁法地球物理勘查并根据勘查区的地球物理特征,最终圈定16个异常区;以16个异常区为重点研究对象,并选取了重点异常区内的磁法剖面进行了2.5维的反演,最终对矿体的形状、规模及埋深进行了预测,指明了下一步的找矿方向。Based on the known mineralization points in the area,the study took magnetic geophysical exploration as the working method,and finally delineated 16 abnormal areas through 1:10000 magnetic geophysical exploration and according to the geophysical characteristics of the exploration area.This paper takes 16 anomaly areas as the key research objects,and selects the magnetic section in the key anomaly areas for 2.5-dimensional inversion.Finally,the shape,scale and buried depth of the ore body are predicted,and the further prospecting direction is indicated.
