在不同的阿拉伯地质档案中发现了早至中全新世湿润阶段，尽管在这一阶段的开始、持续和稳定方面已有显著的区域不均一性。来自阿拉伯联合酋长国(阿联酋)瓦哈拉的多代理湖泊和沙丘记录记录了全新世前半期在水文、生物生产力和景观稳定性方面的重大变化。这些数据表明，末次冰期后的最大沙丘侵位持续到全新世最早部分，从∼8.5ka开始永久的湖泊沉积开始。据推测，在∼7.8亿至5.9亿大卡之间，盆地将长期转向更干旱的状况，盆地间歇性洪水泛滥，整个集水区出现明显的不稳定阶段。这一转变与热带辐合带(ITCZ)的南迁和与之相关的季风雨减弱有关。景观不稳定的峰值出现在∼5.9亿至5.3万亿卡之间，并以区域沙丘侵位显著增加为标志。这些变化与人类住区的记录一起被考虑，提出了关于新石器时代阿拉伯东南部人口统计、气候和环境之间相互作用的重要问题。
An early-to mid-Holocene humid phase has been identified in various Arabian geo-archives, although significant regional heterogeneity has been reported in the onset, duration and stability of this period. A multi-proxy lake and dune record from Wahalah in the United Arab Emirates (UAE) documents significant variations in hydrology, biological productivity and landscape stability during the first half of the Holocene. These data reveal that post-Last Glacial Maximum dune emplacement continued into the earliest part of the Holocene, with the onset of permanent lacustrine sedimentation at the site commencing ∼8.5 ka cal. BP. A long-term shift towards more arid conditions is inferred between ∼7.8 and 5.9 ka cal. BP, with intermittent flooding of the basin and distinct phases of instability throughout the catchment area. This transition is linked to the southwards migration of the Intertropical Convergence Zone (ITCZ) and associated weakening of monsoon rains. A peak in landscape instability is recorded between ∼5.9 and 5.3 ka cal. BP and is marked by a pronounced increase in regional dune emplacement. These variations are considered alongside the record of human settlement raising important questions about the interactions between population demographics, climate and environment in southeast Arabia during the Neolithic.
