摘要
探讨了用于探测异常源边界和形状的Tilt梯度及其水平导数的方法及其性质.通过模型试算,论证了Tilt梯度及其水平导数的有效性,并从理论上给予了证明.Tilt梯度及其水平导数的方法及其性质可广泛用于区域重磁异常的构造解释之中.
We discuss the methods of Tilt derivative (T_(dr)) and the total horizontal derivative of T_(dr) (T_(dr)_Th_(dr)) for locating the boundaries of magnetic or gravity sources in this paper. Through theory analysis and modeling, we prove the effective methods of T_(dr) and T_(dr)_Th_(dr), which can be used in the tectonic interpretation of magnetic and gravity anomalies.
