The foreland-type basins originated mainly in Late Triassic during the convergence of East Tethys and the continental collision, while the extensional and transform-extensional basins formed mainly in the Eastern China in Late Mesozoic and Cenozoic. They are closely related to the subduction Process of Pacific Plate from eat and the collision from southwest. As a sighficat indicator of deep Process of the Earth, the igneous rocks and magmatism offer very important information for the basin dynamic analysis. The evolution of the basins in East China were controlled by the combination and alternation effects from the surrounding Plates of Eurasia and the deep Process.展开更多
