作者首次提出苏皖地块是特提斯演化阶段一个独立的构造单元。基于火成岩及变质岩和古地磁的研究成果认为苏鲁洋在晚侏罗—早白垩世最终闭合 ,苏皖地块与华北克拉通碰撞而出现高原 ,因而中国东部燕山期高原性质上应属碰撞高原。文中还讨论了高原边缘的冲断 -推覆带和其内部的复杂结构 (包括沿主碰撞 -剪切带发育的相对高峻地带和相对开阔的山间磨拉石盆地 ) ,认为该高原是规模宏伟的东亚燕山造山系中变形变质相对弱的部分。高原自早白垩世末起坍塌 ,晚白垩世是东亚燕山造山系的全面坍塌期 ,第三纪时燕山期高原已不复存在。强烈的岩浆活动不仅使苏皖地区 ,也使胶东、小秦岭、赣东北等地的燕山期成矿具明显的区域专属性。晚中生代—新生代的构造事件造成苏皖—黄海地区岩石圈强度低、地热梯度高 ,据此评价了其油气远景 The author first proposed that the Jiangsu-Anhui block is an independent tectonic unit during the Tethys evolution. Based on the results of igneous and metamorphic rocks and paleomagnetism, it is concluded that the Suluoyang eventually closed in the Late Jurassic-Early Cretaceous and that the Jiangsu-Anhui Block collided with the North China Craton, resulting in the plateau. Therefore, the Yanshanian plateau in eastern China should belong to the collision plateau. The paper also discusses the thrust of the plateau margin - the thrust belt and its internal complex structures (including the relative high steep zone along the main collision-shear zone and the relatively open mountain molasse basin), which is considered as the scale The magnificent eastern Yanshan orogenic belt in the deformation of the relatively weaker parts. The plateau collapsed from the end of Early Cretaceous. Late Cretaceous was a complete collapse of the Yanshan orogenic belt in East Asia. The Yanshanian plateau ceased to exist in the Tertiary. The intense magmatic activity not only makes the Yushanian mineralization in Jiaodong, Xiaoqinling, eastern Jiangxi and other places of Shandong and Anhui provinces also have obvious regional specialties. Late Mesozoic-Cenozoic tectonic events resulted in the low intensity of the lithosphere and the high geothermal gradient in the Su-Wan-Huanghai area
