摘要
通过在云南泸水市石缸河地区1∶5万矿产地质调查区开展1∶5万地面高精度磁法测量,对磁测数据进行化极、延拓等处理,并对采集的物性标本磁化率及剩磁进行分类统计,查明工作区磁场分布特征,圈定局部磁异常,圈定了锡钨多金属找矿远景区及建议了异常查证区,显示出高精度磁法测量在矿调工作中具有较好的地质找矿预测效果,为该区下一步锡钨多金属找矿工作提供了较好的依据.
Through the 1∶50000 ground high-precision magnetic survey in the 1∶50000 mineral geological survey area in Shiganghe area,Lushui City,Yunnan Province,the magnetic survey data were processed by reduction to the pole and extension,and the magnetic susceptibility and remanence of the collected physical specimens were classified and counted.The magnetic field distribution characteristics of the working area were identified,the local magnetic anomalies were delineated,the tin-tungsten polymetallic prospecting area was delineated,and the anomaly verification area was suggested.It shows that the high-precision magnetic survey has a good geological prospecting prediction effect in the mine survey work,which provides a good basis for the next tin-tungsten polymetallic prospecting work in this area.
