This paper presents and analyzes paleo-liquefaction features found in the State of Kuwait. The features are cemented sand and gravel-filled dikes of Pleisto–Holocene age with appearance and composition similar to typical “sandstone pipes.” The significant age difference between the cemented dikes and the surrounding loose sand, the size and spatial distribution of the dikes, and the local geologic and hydrologic setting all suggest that the feature probably results from a single large event of seismic origin. Likely hypotheses include shaking during large earthquakes or seiching of tsunami-like waves. Additional research is needed to identify the exact cause of these dike formations, which is important for the purpose of improving seismic risk and vulnerability assessment of the Arabian Gulf countries. The search may also help explain the disappearance of an ancient civilization that lived in the same region approximately seven thousand years ago.

本文介绍并分析了在科威特州发现的古液化特征。其特征是Pleisto-全新世时代的胶结沙子和砾石填充的堤防，其外观和成分类似于典型的“砂岩管”。固结堤防与周围松散的沙子之间存在明显的年龄差异，堤防的大小和空间分布以及当地的地质和水文环境都表明该特征可能是由一个大地震事件引起的。可能的假说包括在大地震中摇晃或海啸状波浪的发动。需要进一步的研究来确定这些堤坝形成的确切原因，这对于改善阿拉伯海湾国家的地震风险和脆弱性评估是重要的。
