岩石和矿石的密度在垂直方向和水平方向常常是变化的.为了更好地对重力异常进行解释,应当研究变密度体的重力异常的正演计算方法.I.V.R.默撒和D.B.罗等曾计算过密度随深度变化、截面不规则的二度体的重力异常.本文提出一种计算三维变密度体重力异常的正演方法.
The density of rock and ore often varies in the vertical and horizontal directions.In order to better explain the gravity anomaly, forward calculation methods of gravity anomalies in variable density bodies should be studied.IVR Moses and DB Luo et al. Have calculated The density changes with depth and the gravity anomalies of second-order body with irregular cross section.This paper presents a forward method to calculate the gravity anomaly of three-dimensional variable density body.
