This work shows the results of computing the 3D density disturbance images in Continent of China and interpretation of the these results based on geodynamics and petrophysics, especially for crust beneath craton terrains. Methods:We apply the scaledepth relationship of gravity anomalies and the multiscale wavelet analysis for extracting crustal density information from surface Bouguer gravity data, and presents density disturbance images of the upper, middle and lower crust, which represent the three dimensional density structures in the studied area. Results:The craton terrains of Continent of China are generally characterized by high density in whole crust, especially having big and highdensity crustal roots; on contrast, orogenic belts usually have lowdensity mountain roots. As current craton terrains usually have long evolution history and different evolutionevent sequences, their crustal structures could be changed diversely. Their evolution might had some different stages and taken millions of years. In different evolutional stages, their crustal physical properties could change greatly. We must endow concepts of certain evolutional stage to the tectonic units in order to understand exactly their behaviors and attributes. From crustal density images one may obtain information about maturity of a craton terrane. The density structures beneath the current craton terrains can be divided into three types: (1) relatively high in whole crust, called as typical craton; Tarim, Alashan, East Huabai, Upper and Middle Yangtze belong to this type. (2) Relatively low in the upper crust, but high in the middle and lower crust, called as weekcrystalline basement craton; Ordos and Jiamusi belong to this type. (3) Relatively high in the upper and middle crust, but low in the lower crust, called lackroot craton blocks; Qaidam and Junggar belong to the third type, they were probably flanks of an ancient craton. Conclusions:The craton terrains of Continent of China are generally characterized by high density in whole crust, especially having big and highdensity crustal roots but including three different types.
