白云岩之谜,是指白云岩的成因而言。它的成因分为“原生派”和“次生派” 两大家。两家各据己见,长期争论不休,才出现了岩石学中的“白云岩之谜”。原生派认为:白云岩是从海水中直接沉淀出来的,次生派认为:白云岩不是从海水中直接沉淀的,而是由海水中的镁离子交代石灰岩中的部分钙离子形成的。原生派为了证实自己的观点,曾想在实验室中,用海水沉淀白云岩,但失败了。由此,次生派一直占统治地位,也称正统派。然而,到本世纪50年代,人们相继在美国的深泉湖、波斯湾、巴哈马、澳大利亚的考尤泻湖、苏联的 Dolomite mystery refers to the cause of dolomite. Its causes are divided into “primary school ” and “secondary school ” two people. The two have each seen, long-standing controversy, it appeared in the petrology “dolomite mystery.” Protists believe that dolomite precipitates directly from seawater. The secondary school believes that dolomite is not precipitated directly from seawater but is formed by the replacement of some calcium ions in the limestone by magnesium ions in seawater. In order to confirm their point of view, the native school tried to sediment the dolomite with seawater in a laboratory, but failed. As a result, the secondary school has always dominated, also known as orthodoxy. However, by the 1950s, one after another in the United States Shenquan Lake, the Persian Gulf, the Bahamas, Australia’s Kauai Lagoon, the Soviet Union’s
