长期以来,人们一直认为能结合有机质的页岩或泥晶灰岩是烃类的源岩。然而,在盐盆地中烃类生成的概念模式并不要求有烃类富集的非渗透性地层、页岩或泥晶灰岩作为油气的源岩。在蒸发岩盆地中,来源于表层水的有机质被保存在密跃层以下的缺氧高盐度卤水中,由于没有水的循环,它们被细菌分解,进入溶液或在底部沉积。蒙脱石、方解石、石膏和碳酸 For a long time, it has been considered that organic matter-bearing shale or micrite is the source rock of hydrocarbons. However, the conceptual model of hydrocarbon generation in salt basins does not require hydrocarbon-enriched, non-permeable formations, shales or marls as source rocks. In evaporite basins, organic matter derived from surface waters is retained in hypoxic, high salinity brine below the thermocline, whereupon they are broken down by bacteria into the solution or deposited at the bottom due to the lack of circulation of water.
