The high-precision magnetic survey explanation of concealed faults in Kamoshite area of Xinjiang

There are widespread Quaternary overburdens in the south of Kamoshite, where there exists a EW-trending positive magnetic anomaly belt about 11km long, which is supposed to be the reflection of basic or ultrabasic material reversed magnetization. In order to give a reasonable explanation, the authors arranged 1∶10000 profiles to trace the strike of the anomaly. Through the fine discrete wavelet processing, the anomalies distributions at different depths were detected. Combined with Euler Deconvolution operation and normalized total gradient domain processing, it is found that the anomaly is mainly caused by fault, which is the extension of the fault caused by Tash Narayan nappe in Kamoshite.
