Mediterranean salt domes formed after crustal movements opened the straits between the Mediterranean and the Atlantic, and the Mediterranean refilled with water.
地壳运动打开了地中海和大西洋之间的海峡,地中海重新被水注满,之后形成了地中海盐丘。
Were they salt domes such as are common along the United States Gulf Coast, and if so, why should there have been so much solid crystalline salt beneath the floor of the Mediterranean?
它们是在美国墨西哥湾沿岸的那种很常见的盐丘吗?如果是的话,为什么地中海海底会有这么多坚硬的结晶盐呢?
Salt domes start during past periods of alternating wet and dry climate.

Salt domes form as a consequence of the relative buoyancy of salt when buried beneath other types of sediment.
盐丘的形成是岩盐埋藏于其他类型的沉积物之下而具有相对的浮力的结果。
For instance, salt domes appear as negative anomalies because rock salt is of a lower density than all consolidated sediments.
例如,盐穹表现为负的重力异常,因为比起所有的固结沉积物,岩盐具有较低的密度。
While many salt domes retain a cap of the youngest rock layers at the surface, in some cases the underlying salt extrudes all the way to the surface.
当许多盐穹挤压年轻的上覆岩层时,有可能原本在下方的盐质会逐渐挤压直至突出地表。
A technique for Marine seismic acquisition around salt domes or other circular features in which the acquisition vessel travels in a spiral path above the feature.

Among such features may be synclines and anticlines, geological faults, salt domes, undulations of the crystalline bedrock under a cover of moraine, ore bodies, clay deposits and so on.
例如向斜、背斜、断层、盐丘,冰碛层之下结晶岩的顶面起伏形态,矿体以及粘土矿床等。
