《贵州省岩石分类命名原则》一书是贵州省地矿局实验室主编的一本基础地质工具书,全书约12万字、图17张、表72张、照片416幅。贵州省是一个沉积岩极为发育的省份,沉积岩类齐全,其中又以碳酸盐分布最广,编写的重点放在沉积岩上。全书将岩石分为28类,现将沉积岩篇中主要岩石分类命名简介如下: 1.火山碎屑岩类 火山碎屑岩的分类,主要以熔岩、正常沉积物与火山碎屑物的相对含量变化;胶结物的种类;碎屑物质的物态和粒度对岩石进行分类命名(表一)。
The book “Principles of Nomenclature of Rock Classification in Guizhou Province” is a basic geological tool compiled by Guizhou Provincial Bureau of Geology and Mineral Resources Laboratory. The book covers about 120,000 words, 17 pictures, 72 tables and 416 photographs. Guizhou Province is a very developed sedimentary province of provinces, sedimentary rock complete, of which the most widely distributed carbonate, written on sedimentary rocks. The book will be divided into 28 kinds of rocks, the sedimentary rock articles are now described in the main rock classification is as follows: 1 volcaniclastic pyroclastic classification, mainly lava, normal sediments and pyroclastic matter relative content change ; The type of cement; the status and granularity of the detritus material classify the rocks (Table 1).
