重力梯度欧拉反褶积及其在文顿盐丘的应用
Euler deconvolution of gravity gradiometry data and the application in Vinton Dome
摘要
Abstract
In the mineral exploration and regional geological survey works,the gradiometry data is widely used because of its high precision.A new gradiometry Euler deconvolution is proposed in this paper combining three kinds of tensors of gravity gradiometry data,which can avoid errors from improperly selecting structural index and tensor transformation in calculations.Building theoretical models of single prism and dual prisms in different depths verifies that the proposed method can accurately inverse geological body depth and horizontal location.This method is applied to gradiometry data in Vinton Dome.The shape and distribution of cap rock top are depicted and new small-scale geological bodies are detected.The results agree very well with the known data,further enriches the underground structure information of this area.关键词
