高精度重力测量经过野外测量、室内计算、整理发现异常后,采用作者三点联测法,于野外在异常中心测得异常区3个不同点重力场强度gA(进行地形改正,中间层改正和高程改正,未减去该测点正常重力值,下同)、gB和gC。运用重力场强度空间变化关系,求取异常源体质量中心埋藏深度;求取异常源体剩余质量;求取异常源体剩余密度、体积和矿石量。 High-precision gravimetric measurement After field measurement, indoor calculation and finishing, after finding the abnormalities, using the author’s three-point simultaneous measurement method, three different gravitational field intensities (gA) were measured in the abnormal center in the field Elevation correction, not to minus the normal gravity of the measuring point, the same below), gB and gC. Using the spatial variation relationship of gravity field intensity, the buried depth of the center of mass of the abnormal source body is calculated; the residual mass of the source body is obtained; and the residual density, volume and ore amount of the source body are calculated.
