利用重力多尺度分解资料反演青藏高原东北缘地壳厚度
CRUST THICKNESS INVERSED FROM MULTI-SCALE DECOMPOSITION OF BOUGUER GRAVITY ANOMALIES IN NORTHEASTERN OF QINGHAI-TIBET PLATEAU
【摘要】 通过重力异常分解模型,选用小波基函数"bior3.7",分解得出青藏高原东北缘布格重力异常资料的小波4阶近似成分,利用其主要由莫霍面产生的布格重力异常,以6条人工地震剖面信息做初始控制条件,反演得出青藏高原东北缘的地壳厚度。
【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 Qinghai-Tibetan 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 Qinghai-Tibetan 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; crustal thickness;
