A foreland basin refers to a sedimentary basin on the edge of a craton with an active orogenic belt in its outside. Its genesis is mainly related to the passive sagging of the craton edge and the structure loading on the side of orogen. The basin has distinct characteristics in its formation and evolution, structural deformation and deposition, and is closely related to the evolution of the orogenic belt. At present, basins of this type have shown enormous potential in oil and gas resources, and become a hot topic drawing great attention of petroleum geologists and structure geologists.
