Abstract: Basin-prototype belongs to the tectonic propertywhen sedimentation occurs. The method of prototype analysis is just used to distinguish one stage basin types from the other stages. Other than working on the volcanical-fault basins of the first circle produced in the late Jurassic-early period of early Cretaceous, this paper discussed on the prototype and sedimentation of red fault basins along the Ganhang Tectonic Belt of the second circle, they produced after late period of early Cretaceous. There is a series of red fault basins at the center of the Ganhang Tectonic Belt, such as the Fuzhou-Chongren Basin, XinjiangBasin, Jinhua-Quzhou Basin and ZhujiBasin, distributing northeastward and mostly contacting each other in there two ends. Combining with the regional extension background manifested by the basalts at the bottom of red beds, these basins started at the late period of early Cretaceous, and almost every basin disp layed an one-tendency fault basin in geometry, which are all restricted within the normal fault in the north and un- conformable boundary in the south. By the middle2late period of late Cretaceous, all basins turned into dep ressive basins, thus the sediments overlay on the basement of the two sides, and there are some self-generating dolomite, marlite and claystone deposit in the centre. In the evolutional process of the red fault basin, the fluvial sedimentation plays a much important role than any other ways of deposition. The sedimentary facies vary from lake facies to fan facies,delta facies and fluvial facies, etc. This assembly is the basic sedimentation type of an extensional fault basin, and the changing model reflects the evolutional process of the fault basin from initial extension (deep lake) to final wither (ground river).
