盐水通常存在于沉积盆地的深处。这些卤水中有许多是自早古生代以来一直存在的原生沃茨。然而，关于它们在地壳深处的分布和保留机制仍然存在疑问。在这里，我们证明，有足够的地形驱动这些致密的流体从深沉积盆地的底部。我们基于驱动力比的评估表明，驱动力比> 1的沉积盆地含有原生沃茨，并经常容纳大型蒸发岩矿床。这些停滞的条件似乎在地质时期相对稳定，对冰川、侵蚀、压实和碳氢化合物生成等因素不敏感。
Brines are commonly found at depth in sedimentary basins. Many of these brines are known to be connate waters that have persisted since the early Paleozoic Era. Yet questions remain about their distribution and mechanisms for retention at depth in the Earth's crust. Here we demonstrate that there is insufficient topography to drive these dense fluids from the bottom of deep sedimentary basins. Our assessment based on driving force ratio indicates that sedimentary basins with driving force ratio > 1 contain connate waters and frequently host large evaporite deposits. These stagnant conditions appear to be relatively stable over geological time and insensitive to factors such as glaciations, erosion, compaction, and hydrocarbon generation.
