摘要：

扬子板块俯冲在华北板块之下,于三叠纪末完成陆-陆碰撞,进入陆内俯冲阶段,在造山带的侧翼形成陆内前陆盆地。此时在苏鲁造山带南侧形成的南黄海盆地即属于陆内前陆盆地(J1—J2),而苏鲁造山带北侧的北黄海盆地和胶莱盆地则缺失这套地层(J1—J2),可能处于隆起状态。从晚侏罗世到早白垩世(J3—K1),中国东部发生广泛火山喷发、岩浆侵位,反映了中国东部构造应力场发生明显的变化。大别-苏鲁造山带南北两侧构造背景有明显的差异。北侧的火山岩特征表明其北侧为裂谷环境,包括北黄海盆地和胶莱盆地,表现为地堑和半地堑形式,高角度平面正断层和犁式正断层发育。晚白垩世—早第三纪,中国东部构造背景又发生了明显的变化,发生大规模的断陷作用。大别-苏鲁造山带晚白垩世发育A型花岗岩,表明造山作用结束,进入造山带崩塌和后造山期,与中国东部总体的伸展期是吻合的。南黄海盆地断陷作用强烈,接受了厚度较大的下第三系;北黄海盆地断陷作用较弱,只在北部小范围内接受了厚度较小的早第三纪沉积。晚第三纪,南黄海盆地和北黄海盆地由于热沉降由断陷变为坳陷。

Abstract:

The subduction of Yangtse plate under the North China plate ended the continental collision and changed into intracontinental subduction at the end of Triassic, resulting in the formation of intracontinental foreland basins on the flanks of Dabie-Sulu orogenic belt.In this period,the South Yellow Sea basin on the southern side of Dabie-Sulu orogenic belt was an intracontinental foreland basin(J1—J2),while the North Yellow Sea basin and Jiaolai basin on the northern side of Dabie-Sulu orogenic belt were probably uplifted,because the Lower and Middle Jurassic sequence is absent.From Late Jurassic to Early Cretaceous,extensive volcanic eruption and magmatic intrusion occurred in the eastern China,indicating the dramatic change of tectonic stress in this region.Tectonic settings were obviously different on the northern and southern sides of Dabie-Sulu orogenic belt.The characteristics of volcanic rocks on the northern side of Dabie-Sulu orogenic belt indicate that this region,including North Yellow Sea and Jiaolai basins,was in a rifting stage,represented by the occurrence of grabens and half-grabens and the development of high angle plane normal faults and listric normal faults.In Late Cretaceous to Early Tertiary,the tectonic setting in eastern China changed obviously into large scale rift faulting.The A-type granite developed in Dabie-Sulu orogenic belt in late Cretaceous,indicating the end of orogenesis and entered into the avalanche period and post-orogenic period of orogenic belt,which was consistent with the extension period in eastern China.Rift faulting was strong in South Yellow Sea basin,where relatively thick Eogene strata was deposited.Rift faulting was relatively weak in North Yellow Sea basin,where thin Eogene strata was deposited only in a small area in the north.The South and North Yellow Sea basins changed from rift to depression due to thermal subsidence in Neogene.

Key words: tectonic setting, tectonic plate activity, high-potassium volcanic rocks, North Yellow Sea basin, South Yellow Sea basin, eastern China
