湿地是古气候和考古工作的重要档案，特别是在干旱地区，因为它们为人类占领提供了一个重点，并保存了环境信息。从'Ayn Qasiyya，在Azraq Qa边缘的春天网站的沉积记录，提供了一个很好的日期序列，通过末次冰期间冰期过渡（LGIT）允许在今天的约旦沙漠的环境变化进行了有力的调查，通过这段时间的第一次。结果表明，最潮湿的时期在网站之前的最后一次冰期最大，其本身的特点是沼泽的形成和一个显着的早期Epipaleolithic占领。16和10.5万年之间的沉积间断表明该地区的干旱期，虽然季节性降雨和地表沃茨仍然允许季节性占领的阿兹拉克地区。考古学证据表明，在晚更新世，大约是北大西洋新仙女木时期，条件得到了改善。在该网站的干湿条件之间的变化显示在地中海东部和阿拉伯半岛的模式相似，这表明约旦内陆的影响，通过LGIT气候过渡在这两个地区的变化。
Wetlands are a key archive for paleoclimatic and archeological work, particularly in arid regions, as they provide a focus for human occupation and preserve environmental information. The sedimentary record from 'Ayn Qasiyya, a spring site on the edge of the Azraq Qa, provides a well-dated sequence through the last glacial–interglacial transition (LGIT) allowing environmental changes in the present-day Jordanian desert to be investigated robustly through this time period for the first time. Results show that the wettest period at the site preceded the last glacial maximum, which itself was characterised by marsh formation and a significant Early Epipaleolithic occupation. A sedimentary hiatus between 16 and 10.5 ka suggests a period of drought in the region although seasonal rains and surface waters still allowed seasonal occupation of the Azraq region. Archeological evidence suggests that conditions had improved by the Late Epipaleolithic, about the time of the North Atlantic Younger Dryas. The changes between wet and dry conditions at the site show similarities to patterns in the eastern Mediterranean and in Arabia suggesting the Jordan interior was influenced by changes in both these regions through the LGIT climatic transition.
