A chronological study was conducted on the Neolithic depositional layers widely known as ‘Rubble layers’ at the Neolithic site ‘Ain Ghazal, Jordan. The aim of this study was to provide new knowledge about the layers, and their deposition, using luminescence dating. Luminescence ages suggests that the rubble layers were deposited in two distinct episodes, the first around 8.2–8.5 ka ago during the Yarmoukian period, and the second during Chalcolithic period around 6.6–7.4 ka ago. The earlier episode is contemporaneous with records of episodic torrential rainfall during an arid period between 8.6 and 8.0 ka ago, supporting the hypothesis of deposition by natural causes such as flash floods.

对约旦艾因加扎勒新石器时代遗址的新石器时代沉积层（俗称“碎石层”）进行了年代学研究。这项研究的目的是利用发光测年法提供有关这些层及其沉积的新知识。发光年龄表明，碎石层是在两个不同的时期沉积的，第一次是在雅尔穆克时期的 8.2-8.5 ka 之前，第二次是在 6.6-7.4 ka 之前的红铜时代。较早的事件与 8.6 至 8.0ka 前干旱时期的偶发性暴雨记录同时发生，支持了山洪等自然原因沉积的假说。
