Abstract

Publisher Summary This chapter provides an overview of the features of the West and Central African rift system(WCARS). The WCARS is a very large scale feature which is distinctive in the sense that it traverses the entire continent. Its complex history involved extension, shearing, and compression over a period extending from the early Cretaceous into the early Tertiary. Portions of its history correlate with changes in plate movements, and the basins which contained major petroleum resources. It is characterized by an unusual amount of subsidence over most of its extent which obscured many rift structures. The region is an ideal place to investigate the interaction of extension and shear during major rifting events.
