摘要

摘要: 从盆—山耦合关系角度研究大别造山带与合肥侏罗纪盆地的性质,提出伴随着大别山的第二次隆升,早侏罗世大别山北缘出现了最强的沉降—沉积,形成了合肥侏罗纪前陆盆地;随后中—晚侏罗世时盆地南部沉降—沉积强度显示出变弱的趋势,期间没有再出现沉降—沉积再加强的现象。简要介绍了盆地不同地区侏罗纪地层的沉积物特征及发育特点,在此基础上,从盆地结构、沉积物碎屑骨架组分、层序结构、沉积体系等角度研究了合肥侏罗纪盆地对大别造山带的响应,指出二者之间具有较好的耦合关系。

Abstract: Characteristics of the Hefei Jurassic Basin and the Dabieshan Orogenic Belt have been studied from the aspect of basin-and-range coupling in this paper.With the second uplifting of the Dabieshan Mountain,the northern fringe of the Dabieshan Mountain underwent the strongest subsidence and sedimentation in the early Jurassic and then the Hefei Jurassic Foreland Basin was formed.Afterwards,the subsidence-sedimentation process slowed down gradually in the south of the Hefei Basin in the Middle-Late Jurassic without any strengthening phenomenon.The authors also briefly introduce the sediment characteristics of the Jurassic Formation in different areas of the Hefei Basin.On this basis,the sedimentary response to the Dabieshan Orogenic Belt of the Hefei Jurassic Basin is studied thoroughly from the aspects of basin structure,clastic matrix constituents of sediments,sequence architecture and sedimentary system,and so on.The study demonstrates that these two things are coupling very well.
