Hearth sites are characteristic of Holocene occupation in the Arabian sand seas but remain mostly unstudied. Excavations of two multi-period hearth sites in the Jebel Oraf palaeolake basin, in the oasis of Jubbah, now substantially increase our knowledge of these sites. In total, 17 of 170 identified hearths were excavated at Jebel Oraf 2 (ORF2), an open-air site on the edge of a palaeolake. In addition, 11 hearths were excavated at the stratified site of Jebel Oraf 115 (ORF115), a rockshelter formed by two boulders. Radiocarbon dating and lithic assemblages indicate that the majority of these hearths were in use in the second half of the 6th millennium BCE, and that both sites were used sporadically until the recent past. All hearths appear to have been extremely short-lived, and faunal remains suggest they may have been used to cook meat from hunted or trapped wildlife, and occasionally from livestock. The frequent use of grinding stones, often broken into fragments and used to cover hearths is also attested. Evidence for the exceptionally early use of metal from dated occupation deposits as well as from rock art, shows that these short-lived sites were well connected to technological innovations in the wider region.

炉床是阿拉伯沙海全新世占领的特征，但大部分尚未研究。在Jubbah绿洲的Jebel Oraf古湖泊盆地中的两个多期壁炉床遗址的发掘，现在大大增加了我们对这些地点的了解。总计在170个已确定的炉膛中，有17个是在古湖边缘的露天场所Jebel Oraf 2（ORF2）处发掘的。此外，在Jebel Oraf 115（ORF115）的分层地点开挖了11个炉膛，Jebel Oraf 115是由两个巨石组成的岩石棚。放射性碳年代测定法和岩性组合表明，这些炉床中的大多数在公元前6世纪下半叶使用，并且直到最近为止都偶尔使用这两个炉灶。所有炉膛似乎都是短暂的，动物区系遗迹表明，它们可能被用来烹饪被猎杀或被困野生动物的肉，偶尔还可以用来饲养牲畜的肉。也证明了经常使用的碎石，这些碎石经常被破碎成碎片并用来覆盖炉膛。从过时的占领矿床和岩石艺术品中特别早期使用金属的证据表明，这些寿命短的地点与更广泛地区的技术创新息息相关。
