摘要: 线性构造识别是区域重力资料解释中的重要一步。本文介绍了用于探测重力异常边界和场源深度的Tilt梯度法;同时,应用Tdr零值线及±π/4曲线距离半值或零值与+π/4(或-π/4)曲线距离对研究区重力异常源的位置和埋深进行了推断,并把推断结果与区内大地电磁测深剖面解释成果进行了对比。结果表明,应用Tilt梯度对区域重力资料进行线性构造识别是可行的。Abstract: The identification of linear structures is an important step in interpretation of regional gravimetric data.In this paper,we introduce the method of Tilt-angle derivatives for detecting of boundaries of gravity anomalies and depths of gravity field sources;besides,the location and depths of gravity field sources are inferred using zero Tdr contours,and half distances between +π/4 contours or distances between zero and +π/4 or-π/4 contours of Tdr,and the results are compared with the interpretation of the magnetotelluric vertical sounding profile of the studied area.The results show that the identification of linear structure in interpretation of regional gravimetric data by using of method of Tilt-angle derivatives is feasible.
