| 摘 要： | 大别造山带北麓地区位于大别造山带外侧缘,其构造演化过程严格受大别造山过程的控制。大别造山带北麓地区构造热史的恢复对于整个大别造山带造山过程的研究具有重要意义。造山带外缘复杂的构造演化过程,造成了其埋藏史恢复的复杂性。在综合分析该地区石炭系上覆地层分布、侵入岩中矿物结晶压力以及构造运动发展阶段等多方面资料的基础上,以全新的思路恢复了大别造山带北麓地区石炭系埋藏史,分析认为,自石炭纪以来,大别造山带北麓地区共经历了三次沉降和三次隆升的演化过程。

| Abstract: | The north foothills of Dabie orogenic belt is located in the outside margin of Dabie orogenic belt.Its structural evolution is extremely controlled by the orogenic process of Dabie orogenic belt.The reconstruction of the tectonic-thermal history in the north margin area is significant to the study of the entire orogenic process of Dabie orogenic belt.On the basis of the systematic study of the strata above Carboniferous,the mineral crystallization pressure in the intrusive igneous rock,and the structural evolutional phase in the north margin area,this paper reconstructs the evolutional history and suggests the evolutional model.It is considered that the north margin area of Dabie orogenic belt has undergone three subsidences and three denudations since Carboniferous. |
