几年来,我们配合钾盐研究工作,先后调查了南方四省(粤、桂、浙、闽)以及湖北、山东、新疆等地的第三纪含盐系及其成钾条件。在有关单位的支持和协助下,观察和收集了一些地层剖面、钻孔岩芯和许多技术资材。 本文编写过程中袁见齐教授亲自审阅初稿,特此致谢。 一、盐岩地层中的沉积同期构造 盐岩地层中的沉积同期构造是一种原生构造,相当于一般所称的同生沉积构造。最特征的沉积同期构造是平行层理构造,在盐岩地层中这种包含有少量泥质的纹层很普遍。湖北江汉第三系盐岩段中由泥纹表现
In recent years, with the research on potash, we investigated the Tertiary salt system and its potassium-forming conditions in the four southern provinces (Guangdong, Guangxi, Zhejiang and Fujian) and in Hubei, Shandong and Xinjiang. With the support and assistance of relevant units, some stratigraphic profiles, core drilling and many technical materials were observed and collected. During the preparation of this article, Professor Yuan Yuanqi personally reviewed the first draft and hereby thanks. 1. Deposits in Salt Rock Stratum Sedimentary sediments in salt rock formations over the same period are a protolithic structure equivalent to the so-called syngenetic sedimentary structure. The most characteristic sedimentary contemporaneous structure is a parallel bedding structure, which is common in salt rock formations with a small amount of shale. Tertiary salt rocks in Jianghan of Hubei Province are characterized by mud patterns
