摘　　要：研究和寻找隐伏以及半隐伏中酸性岩体对深部找矿工作具有重要的指导意义。本文以重力资料为主,结合航磁、地球化学及地质资料,对研究区隐伏和半隐伏中酸性侵入岩体进行圈定,并利用重力数据对圈定岩体进行三维反演,获取岩体的三维空间赋存状态,对其三维空间形态进行定量分析,并结合相关资料综合分析岩体与矿产的关系,对贵州省中东部地区深部找矿具有重要的指导意义。With the higher exploration level of resources and the decreasing of surface mine,it is of great significance to find and delicate concealed and semi-concealed intermediate-acid intrusive bodies in the mineral exploration. Based on the regional gravity data,combining with magnetic data,geochemical data and previous geological research,we indentified concealed and semi-concealed intermediate-acid intrusive bodies,and obtained their three- dimensional spatial shapes by three dimensional inversion,quantitative analyzed their three-dimensional spatial shapes and the relationship with mineral,finally provides important information for deep prospecting.
