中文摘要	全球蒸发岩从震旦纪到新近纪均有发育,其最发育时期为震旦纪一寒武纪、二叠纪一三叠纪以及侏罗纪一白垩纪,且具有幕式分布特点。它们在一定区域(低纬区)常大规模集中发育,跨越不同的沉积盆地类型,面积和厚度巨大,时代跨度较短且连续,笔者称之为巨量蒸发岩省。本文基于全球蒸发岩层系古板块再造、沉积岩相恢复、地层柱状对比、盆地构造分析等方法,对巨量蒸发岩省的发育、分布、成因及其地质意义进行了探讨。巨量蒸发岩省形成、分布与地史中的造山带演化、超大陆的聚合与裂解、干旱气候带(南北纬30°之间)、海平面变化等因素有着密切联系;其主要形成于干旱环境下相对封闭、靠海水潜流补给的台地和盆地中;所处的构造单元主要为泛大陆板块内部狭长的裂谷带、特提斯造山带的残余洋盆、海一陆过渡带、陆表海或孤立板块的台地中心。
英文摘要	Evaporates widely developed from the Sinian to Neogene, especially in Sinian-Cambrian, Permian-Triassic, and Jurassic-Cretaceous. They always developed on large-scale in low latitude sedimentary basins with different types, having large area and sedimentary thickness, and they developed continuously in short time period. In this paper these evaporation basins were called saline giants. Based on the reconstruction of paleoplate and sedimentary lithofacies, the stratigraphic correlation and structure analysis of evaporation salt basins, the paper had discussed the development, distribution and geologic genesis and significance of global saline giants. The evolution of orogenic belt, the assemblage and breakup of supercontinent, the arid climate zone (between 300 N and 30° S), the changes of sea level and other factors had important influence on the development and distribution of saline giants. The saline giants developed in relatively closed plateaus and basins with recharge of subsurface seawater in arid environment. The saline giants generally distributed in the narrow rift belt inner continental plates, remnant oceanic basins in Tethyan orogenic belt, sea-land transitional zones, epicontinental sea and platform center of isolated plates.
