Abstract：The study of gravity anomaly and Moho fluctuation characteristics in Jiangxi Province and its adjacent areas is of great significance to the exploration and development of mineral resources in this area.In this study,based on the Bouguer gravity anomaly data in Jiangxi Province and its adjacent areas,the wavelet decomposition detail field and approximation field of Bouguer gravity anomaly were obtained by using the wavelet multi-scale decomposition method.On this basis,the Moho depth was obtained by using the Parker-Oldenburg iterative inversion method.The results show that from northwest to southeast,the Bouguer gravity anomaly and its wavelet approximation field present the variation characteristics of median-low-high value,corresponding to the Yangtze Block,the Cathaysia Block,and the Taiwan Strait,respectively.The Dabie orogenic belt and the Taiwan Strait can be easily identified according to the Bouguer gravity anomaly and its wavelet detail field and approximation field.The Moho depth varies between 29 and 36 km,showing three levels of moderate-deep-shallow variation from northwest to southeast,corresponding to the Yangtze Block,the Cathaysia Block,and the Taiwan Strait,respectively.
