Orogenic Sedimentology Series I-Sedimentions in the Forearc of Orogenic Belts

Since the widespread acceptance of the plate tectonics theory by geology community,much attention has been paid to sedimentology during investigating the orogenic belts. On the basis of summarizing the three main development stages of the plate tectonic sedimentology and several excellent individual researches,in this paper,we firstly focus on illustrating the definitions of trench basin,wedge-top basin and forearc basin in arc orogenic belt,and then explicitly introduce sedimentary environment,assemblage and provenance of three kinds of basins with specific examples. In summary,these discussions can serve as general introductions to the readers about the orogenic sedimentology.
