Lithologically different rock sheets intertexturally superimposed with faults and folds of various styles . while , the southern belt is chiefly of devonian tuff , tuffaceous schist , marble relatively stable in strata and manifested by regional asymmetric fold easi - westward in axis , with well developed superimposed overthrust south - northward which controlled the whole structural framework in this area 南带以泥盆系凝灰岩、凝灰质片岩、大理岩为主,地层相对稳定,表现为轴向东西的区域性不对称褶皱,广泛分布控制全区构造格局的南北向逆冲推覆的叠瓦式断裂。
This paper analyzes the sedimentation and the occurrence of the strata in wuxia area and suggests that wuxia area underwent the development of foreland basin of early permian , the overthrust nappe of late permian , the strong structural uplift of late triassic , the weak structural activity of late jurassic and the structural shape of cretaceous followed by finally forming the configuration nowadays 在对乌夏地区地层的沉积特征和产状分析后发现,乌夏地区经历了早二叠世的前陆盆地发育阶段、二叠纪末的逆掩推覆,三叠纪末的构造强烈隆升、侏罗纪末期的构造微弱活动、至白垩纪的构造定形等多个阶段的演化而形成了现今的面貌。
