Abstract With a gravity anomalies decomposition model, and through using the wavelet function “bior3.7” ,the fourth order wavelet approximate components of the Bouger gravity anomalies of northeast margin of the QinghaiTibetan Plateau can be obtained.Furthermore,by utilizing the Bouger gravity anomalies come from the Moho and taking the information from the 6 artificial profiles as the initial control conditions,the crustal thickness of northeastern margin of the QinghaiTibetan Plateau is inversed, and the inversion results are analyzed and discussed according to the crustal thickness distribution features.
Key words :
gravity anomaly
northeastern margin of the Qinghai-Tibetan Plateau
wavelet analysis
inversion
