层状蒸发岩形成于三种基本沉积环境:(1)深水湖,这种湖一般有密度分层,如死海;(2)浅水湖、泻湖,如美国的大盐湖;(3)暂时性盐坪(干盐滩),如美国加利福尼亚的死谷。根据主要蒸发岩矿物的不同,盐坪可分为石盐坪、天然碱坪、石膏坪等。据现代盐坪的观察和研究,综合出了盐坪沉积的一系列特征,可作为蒸发岩盐坪的辨认标志。 Stratiform evaporites are formed in three basic sedimentary environments: (1) deep-water lakes, which generally have densities such as the Dead Sea; (2) shallow lakes, lagoons, such as the Great Salt Lake in the United States; (3) temporary salts Ping (dry salt beach), such as Death Valley, California, USA. According to the main evaporite rock minerals, salt Ping can be divided into Shilin Ping, natto Ping, gypsum Ping. According to the observation and research of the modern salt Ping, a series of features of the Yanping sediment are synthesized and can be used as the identification mark of the salt rock Ping.
