Abstract

The paper presents the results of studying sylvinite rocks of the Lower Permian halogenic formation in the West and East Perelyub sites with perspectives for the commercial development of potassium salts in the Saratov region and in the Gremyachinsk potash deposit (Volgograd region, Russian Federation) by the textural–structural analysis methods to refine their formation conditions. A new method is proposed for studying the structural–textural features of sylvinites and sylvite–halite rocks. Typification of sylvinite structures and identification of the main genetic types of their texture are accomplished. Based on the literature data and the results of studying the core material, a scheme of the structure–texture classification is proposed for the chemogenic-sedimentary potassic rocks, including those subjected to postsedimentary transformations.

里海盆地早二叠世钾盐岩结构-结构外观的成因解释

摘要

本文介绍了对西和东 Perelyub 地区下二叠统卤化地层钾盐岩的研究结果，并为萨拉托夫地区和格雷米亚钦斯克钾盐矿床（俄罗斯联邦伏尔加格勒地区）钾盐的商业开发提供了前景。结构-结构分析方法来细化它们的形成条件。提出了一种研究钾盐和钾盐-岩盐岩石结构-结构特征的新方法。钾盐结构的典型化和其质地的主要成因类型的识别已经完成。根据文献资料和岩心材料研究结果，提出了化学成因-沉积钾岩，包括沉积后转变的结构-结构分类方案。
