| 摘 要： | 等效源法曾被广泛应用于卫星磁异常解释,而本文是将等效源法引用到航空△T磁场的解释中,用其研究区域地质构造。根据等效源法的理论,推导出球坐标系下球棱柱体的△T磁场公式,采用线性反演的方法进行模型验证,同时将该方法用于秦巴地区航空△T磁异常的试算,得到了一些有意义的结论。利用该方法可由所求得的磁场强度来得到居里深度分布。

| Abstract: | Abstract The equivalent &ource method has been extensively used ia the interpretation of satel-
lite magnetic anomalies. Ia this paper, however, the equivalent source method is introduced
into the interpretation of the aarbmagnetic AT field to investigate regional tectonics. Based on
the theory of the equivalent source method, we deduced a formula for Ar magnetic field of the
lower spherical prism of the spherical coordinate system, and made model test using the linear
inversion method. This method was used to make tentative calculation of aeromagnetic T ano-
malies in Qinlins-Bashan area and, as a result, reached some valuable conclusions. With this
method, the Curie depth distribution can be obtained from the calculated magnetic field inten-
sity. |
