地质地球物理成果的分析表明,北淮阳地区为一俯冲壳楔,体现为广布糜棱岩和碎裂岩带的具有多层次多级别滑脱面的块片构造格局。地壳运动,自大别活化基底,北淮阳俯冲壳楔、华北陆块等依次由南向北仰冲。换言之,由北向南发生A式陆内俯冲, Geophysical and geophysical results show that the Beihuaiyang area is a subduction shell wedge, which is characterized by a broad mylonite and cataclastic zone with multi-level multi-level slip surface. Crustal movement, activation of the basement from the Great Paleo-Mahui, the North Huaiyang subduction shell wedge, the North China land block followed by the South to North Yang Chong. In other words, A-type intracontinental subduction occurs from north to south,
