Extensional subsidence, stable depression and extrusion inversion are three stages generally going through in the inversion structure. The faults connected with the source rocks are overlaid by various anticlines caused by the tectonic inversion, with a very interesting relationship among transportation, generation and reservation. The inversion structures were extensively studies. This paper focuses on the inversion structure styles of strike-slip B basin in African, including the concept evolution of inversion tectonics, the types of inversion tectonics, the identification of inversion tectonics, and the inversion rate. Several existing problems of the inversion structure are discussed. It is shown that, the styles of the inversion structure are mainly classified based on the influence and the control of the faults and fold structures. The tectonic inversion should be identified based not only on the analysis of the regional event, but also on the features of folds and faults and the activity history. The degree of the tectonic inversion can be described qualitatively and divided into three levels: the slight inversion, the moderate inversion and the strong inversion based on the deformation characteristics of the reverse faults and folds. The inversion rate can be calculated to quantify the degree of inversion accurately.
