利用小波细节的微分特征对重力场进行断裂分析。理论分析和模型计算结果表明,小波细节具有水平一阶导数的特征,利用该特征对地质体边界的重力场进行小波变换,并结合频谱分析方法估算重力场小波的场源深度,由此可获得不同深度上断裂的空间位场及特征。与传统的向上延拓和求水平一阶导数来分析断裂的方法相比,该方法克服了向上延拓异常特征模糊化,使重力场的断裂分析更加准确和可靠。应用该方法分析了东秦岭地区的断裂分布。
Fracture Analysis of Gravity Field by Using Differential Features of Wavelet. The theoretical analysis and the model calculation results show that the wavelet detail has the characteristics of the horizontal first derivative. By using this feature, the gravity field of the boundary of the geological body is transformed by wavelet transform. The field depth of the gravity field wavelet is estimated by the spectrum analysis method. Fracture Site and Characteristics at Different Depths. Compared with the traditional method of upward continuation and horizontal first order derivative to analyze faults, this method overcomes the fuzzification of the upward continuation anomalies and makes the fracture analysis of the gravitational field more accurate and reliable. This method is used to analyze the fracture distribution in the East Qinling area.
