Origin and development of sequence stratigraphy

Sequence stratigrphy is evolved from seismic stratigraphy, and has found wide use in petroleum and other sedimentary resources exploration in the world. Currently, there are probably three research groups that are undertaking the sequence stratigraphy study: Exxon group represented by Vail et al., Galloway represen ted by Galloway, and Cross's represented by Cross. They share some terms of sequence stratigraphy, but they have their own conceptual model and study ways for sequence stratigraphy. This paper tries to analyze the origin and the evolution of sequence stratigraphy, and features and predominance of these research groups.
