依据岩石结构和矿物成分相结合并参照成因的原则,本文提出一个构造岩分类命名新方案。大体分为六大类:(一)角砾岩—磨砾岩类,后者是对压扁,滚动和园化的断层角砾岩的一个新的命名。(二)碎裂岩类,再细分为碎斑岩、碎粒岩和碎粉岩,其粒级相当于沉积岩中的粗砂、细砂和细粉砂。(三)糜棱岩类,又划分出粒化岩、粗糜棱岩和超糜棱岩,其粒级可与碎裂岩类相对比,但均具优选方位。(四)千枚糜棱岩类,按结构特点还详分为千枚糜棱岩、变余糜棱岩、硬板岩、变晶糜棱岩和片麻糜棱岩等。(五)构造片岩类,与区域变质岩中的片岩和千枚岩极其相似,故可用变质岩的一般命名原则分类。(六)玻化岩类,系剧烈变形高温熔融又迅速冷却的产物。构造岩的形成都是同构造运动、力学性质密切相关的。
Based on the principle of rock composition and mineral composition combined with reference to genesis, a new scheme for nomenclature and classification of tectonic rocks is proposed in this paper. There are six general categories: (a) breccia-rubble conglomerates, a new nomenclature for crushed, rolled, and zoned faulted breccias. (II) Fragmented rocks, further subdivided into porphyry, granulite and brecciated rock, the grain size of which corresponds to coarse sand, fine sand and fine silt in sedimentary rocks. (Iii) Mylonites, also classified as granulite, coarse mylonite and extra-mylonite, with grain fractions comparable to those of clastic rocks but with preferred orientation. (D) a thousand mylonites, according to the structural features are further divided into a thousand mylonites, metamorphic mylonites, hard slate, metamorphic mylonites and gneiss mylonites and so on. (E) tectonism, which is very similar to schist and phyllite in the regional metamorphic rocks, so it can be classified according to the general nomenclature of metamorphic rocks. (F) vitrified rocks, the Department of severe deformation of high-temperature melting and rapid cooling of the product. The formation of tectonism is closely related to tectonic movement and mechanical properties.
