线性构造的识别是区域重力资料解释的重要环节。本文介绍了利用倾角导数法探测重力异常边界和重力场震源深度的方法，并利用零TDR等值线、+π/4等值线之间的半距或+π/4或-π/4等值线之间的距离来推断重力场震源的位置和深度，并与研究区大地电磁垂直测深剖面的解释结果进行了对比。结果表明，利用倾角导数法在区域重力资料解释中识别线性结构是可行的。
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.
