摘要:

造山带沉积地质学是融造山带地层学、沉积学、大地构造学及地球物理、地球化学等为一体的综合性分支学科,被誉为近年来自层序地层学诞生之后,沉积学领域又一次Bench-mark式的跃进。本文着重介绍了造山带沉积地质学研究中应坚持以活动论思想为指导,借鉴沉积盆地分析中整体分析、综合分析、背景分析和演化分析的学术思想和工作原理,并结合造山带结构和盆地及古海洋格局,确定造山带沉积地质学研究内容和技术路线。造山带沉积地质学包括造山带区域地层学、区域沉积学、区域构造学、地层层序和沉积演化、古地理和古海洋格局、动力沉积学和动力演化模式等内容和多层次综合研究的技术路线。

Abstract:

Sedimentary geology of orogenic belts famed another benchmark in sedimentology since the emergence of sequence stratigraphy,is a synthetic branch of science including stratigraphy,sedimentology,tectonics,geophysics and geochemistry.In this paper,em-physis is laid on the theoretical train of thoughts and methodology for the study of sedi-mentary geology of orogenic belts,adopting the entire analysis,synthetic analysis,back-ground analysis and evolution analysis in basin analysis under the guidance of the mobil-ism,as well as on the selection of the contents and steps on the basis of the architecture of orogenic belts and the distribution patterns of basins and oceans.Most contents and multi-disciplinary approaches of regional stratigraphy,sedimentology,tectonics,stratigraphic successions and sedimentary evolution,palaeogeography palaeo-oceanography as well as dynamic sedimentology and evolutionary patterns are involved in the study of sedimentary geology of orogenic belts.
