| 摘 要： | 大别山北缘北淮阳地区中生代逆冲推覆构造作用使本区广泛发育的以下古生界为主体的中、浅变质构造地层，在数百公里的范围内向ＮＥ逆冲（掩）于石炭系和中侏罗统之上，形成一系列构造窗、飞来峰和逆冲（掩）断层带，其最小逆冲推覆距离平均为２４４ｋｍ，形成时代介于Ｊ２—Ｊ３之间，其形成与大别造山带的碰撞挤压有关，是大别地块中生代向北仰冲作用的结果。

| Abstract: | Mesozoic thrusting in northern Huaiyang region, in northern edge of Dabieshan, caused mid to shallow metamorphic structural strata of mainly Early Paleozoic age, widely developed in the area and extending over several hundreds of kilometers, to overthrust NE ward on rocks of Carboniferous and Jurassic ages. This thrust and nappe tectonics are characterized by a series of tectonic windows, klippen, and thrust to overthrust faults, with minimum horizontal displacement of about 24 4km in average, mainly occurred during mid to late Jurassic period. The thrust tectonics resulted from a northward obduction, during Mesozoic, of the Dabieshan block, concomitant with the development of the Dabieshan collisional orogenic belt. |
