中国大陆的华北、塔里木、准噶尔－兴安、华南及甘青藏等五大板块发展过程中于地块边缘活动带、陆间裂谷、陆内裂谷等场所生成的含盐盆地，沉积了各时期（Ｏ、Ｃ、Ｔ、Ｊ－Ｅ和Ｑ）盐类矿床。通过分析对比认为，甘青藏板块兰坪－思茅拗陷带（Ｊ２－Ｅ１、Ｑ），塔里木板块（Ｃ、Ｋ－Ｅ、Ｑ），华北板块（Ｏ２），华南板块（Ｔ１－２）为成钾有利地带，中国东部众多的Ｋ－Ｅ红层盆地中成钾条件较差 During the development of the five major plates in North China, Tarim, Junggar-Xing’an, South China and Ganqing-Tibet in mainland China, the salt basins formed in the marginal activity zones, land rifts and intracontinental rifts have been deposited in various periods O, C, T, J-E and Q) salt deposits. Through analysis and comparison, it is concluded that the Lanping-Simao depression belt (J2-E1, Q), the Tarim plate (C, K-E, Q), the North China plate (O2) and the South China plate (T1-2) In the favorable potassium zone, the K-E red beds in the eastern part of China are poorly potassic
