摘要

摘要通过实验研究了结晶和沉淀的氟化钙在海水和盐水蒸发浓缩第一阶段（石膏和海绿石开始形成之前）的溶解度。结果表明，在所研究的整个盐度范围内，海水及其衍生物中的氟化钙含量严重不足，这就排除了氟化钙在干燥的孤立海盆中自发沉淀的可能性。沉积萤石形成的一个必要条件是大量溶解的氟从外部来源进入干燥的海盆，这些来源可以是河流径流、火山喷发物和热液溶液。

The Solubility of CaF2 in Seawater of Normal and Increased Salinity (Associated with Genesis of Fluorite in Sedimentary Rocks)

Abstract

The solubility of crystalline and precipitated calcium fluoride in seawater and brines of the first stages of its evaporative concentration (before the beginning of gypsum and halite setting) has been experimentally studied. It is established that in the entire studied range of salinity, seawater and its derivatives are strongly undersaturated in calcium fluoride, which excludes its spontaneous precipitation in drying isolated sea basins. A necessary condition for the formation of sedimentary fluorite is the entry of significant amounts of dissolved fluorine from external sources, which can be river runoff, volcanic emanations, and hydrothermal solutions, into drying sea basins.
