盐类物质来源盐类矿床的物质,主要来源于大洋水和大陆水。盐源盆地的岩盐,在中三迭世晚期(白山期),盐井沟北崖山一带为海盆(泻湖)边缘,海水动荡(即稳定中之不稳定),物质来源于外海。少量的早期菱镁矿岩屑及砂岩碎屑等陆源物的混入,只能说明是海浪袭击古陆和先成岩层的结果。石灰岩的微波状层理和硬石膏斑块内部的层状构造,表明了海水荡漾,卤水浓缩、淡化及气温季节的变化。菱镁矿、钙芒硝和自 Salt material Salt mineral deposits material, mainly from the ocean water and continental water. The salt rocks of the Yanyuan Basin are characterized by sea water turbulence (ie instability) in the late Middle Triassic (Baishan period) and the north cliff mountain area of ​​Yanjing ditch as the edge of the sea basin (lagoon), with material originating from the open sea. The small amount of early magnesite cuttings and the inclusion of terrigenous materials such as sandstone clasts can only indicate the result of waves attacking the ancient continents and pre-emplaced formations. The microwave-like stratification of limestone and the layered structure within the anhydrite plaque indicate seawater ripples, brine concentration, desalination and seasonal changes in temperature. Magnesite, Glauber’s salt and from
