摘    要:造山带动力沉积学是造山带地质学和大陆动力学研究的重要方面。造山带动力沉积学研究的重要基础是识别造山带的原型沉积盆地,认识其大地构造沉积相和原型沉积盆地的演化。造山带动力沉积学研究的主要内容包括造山带区域地层学、沉积学、大地构造学、造山带原型盆地的充填序列或构造层序、古地理和古海洋及建立沉积盆地的动力模式。其研究方法涉及造山带原型盆地的物源和组分分析、沉积相和沉积体系及沉积构型分析、充填序列和构造层序分析、古流向和古地理分析、沉积厚度和沉降分析以及沉积盆地动力模拟等。

关 键 词:造山带  沉积学  动力沉积学  大地构造沉积相

Abstract:Dynamic sedimentology of orogenic belts is an important aspect for the research on continental dynamics and geology of orogenic belts. The foundation for the study of the dynamic sedimentology of orogenic belts is to distinguish the original basins in orogenic belts, to re ̄cognize their tectono sedimentary facies and their tectonic evolution. The major contents of dynamic sedimentology of orogenic belts include regional stratigraphy, sedimentology, tectonics, infilling succession or tectonic sequences, palaeogeography and paleo oceanogaphy, as well as the building up of the dynamic model of original basins. The research methods for the dynamic sedimentology of orogenic belts comprise composition and provenance analysis of sediments, sedimentary system and architecture analysis, infilling succession and tectonic sequences analysis, palaeocurrent and palaeogeography analysis, thickness and subsidence analysis, and also the dynamic modeling of sedimentary basin, etc.
Keywords:orogenic belts   sedimentology   dynamic sedimentology   tectono sedimentary facies
