The orogenic strata have following characteristics: During the subduction and intracontinental orogeny, the strata experienced dramatic tectonic migration and mixing, resulting in various tectonic features. A short sequence usually composed of tectonic slices of various origins, times, deformations and metamorphisms, and scales. The original sequence was badly destroyed. The extant fragments of orogenic belt usually took form as melanges, especially the accretion complex wedge generated in subduction zone, which is contrary to the Law of Superposition. The original location of the accretion is also contradicted with the Law of Original Horizonality, because the accretion is oblique with high degree. Marine rocks, volcanic rocks of continental margin and metamorphic rocks were well-developed in the orogenic belt, especially ultra-basic, basic rocks were wide spread and were intensely metamorphosed, accompanied by metamorphic slices returned from hundred kilometers underground with ultra-high pressure and magma movements during syn-orogeny and post-orogeny, thus formed the colorful landscapes.

造山带非史密斯地层构成具如下独特性和复杂性：造山带在俯冲碰撞和陆内造山阶段，发生过强烈的构造搬运和构造混杂，构造形迹多样化，垂直不长的地层体往往是众多不同来源、不同时代，不同变形变质程度，不同大小的各种构造岩片拼贴体，地层原始层序被严重肢解、破坏；尤以产于俯冲带的俯冲增生杂岩楔的原始形成方式与史密斯地层学的&层序叠覆律&老下新上的顺序正好相反，其混杂岩增生方式是老的&片体&在上，新的&片体&阶段性拼贴在老的&增生片体&的斜下方，这种增生片体的原始位置亦与&原始水平律&相悖，即增生片体一般保持较高角度倾斜；在岩石类型和变质程度上，造山带海相和古陆缘火山岩以及变质岩普遍发育，尤其是超基性、基性岩系分布广泛，变质作用较强，伴有从百余公里以下深部超高压变质岩片的折返和同造山期与造山后期岩浆活动，构成极为复杂的地质景观。
