本文主要是介绍结构分类。从结构观点看,碳酸盐岩由颗粒、泥、胶结物、晶粒以及生物格架五种结构组分组成。根据岩石中各种结构组分的特征及其相对含量,可把石灰岩划分为三大类,即Ⅰ,颗粒-灰泥石灰岩;Ⅱ,晶粒石灰岩;Ⅲ,生物格架-礁石灰岩。第Ⅰ大类石灰岩根据颗粒与灰泥的相对百分含量进一步分类,划分为颗粒石灰岩、颗粒质石灰岩、含颗粒石灰岩和无颗粒石灰岩四类。
This article mainly introduces the structure classification. From a structural point of view, carbonate rocks consist of five structural components: grain, mud, cement, grain, and biological framework. According to the characteristics of the various structural components in the rock and their relative contents, the limestone can be divided into three categories, namely, Ⅰ, particle-stucco limestone; Ⅱ, grain limestone; Ⅲ, biological framework-reef limestone. According to the relative percentages of granule and stucco, limestone of category I is further classified into four types: granular limestone, granular limestone, granulated limestone and non-granular limestone.
