摘要: 板块构造理论得到地学界广泛接受以来,沉积学在造山带研究中得到了普遍的重视。笔者在归纳总结板块构造沉积学3个主要发展阶段及其相应的研究成果的基础上,重点讲述了弧造山带的弧前海沟盆地、楔顶盆地和弧前盆地的定义,并结合具体实例介绍了3类盆地沉积环境、沉积组合与物源背景。总之,希望这些讨论能使对造山带沉积学感兴趣的读者得到梗概的认识。

Abstract: 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.
