The zinc-lead-silver deposit of al-Jabali, about 65 km northeast of Sana'a in Yemen, has been identified as the location of the late antique/Islamic period silver mine al-Radrad. Exploitation of the mine is known from the account of al-Hamdani, an Arab geographer of the tenth century AD. The al-Jabali area has been the focus of geological and archaeometallurgical surveys, and extensive metallurgical remains have been discovered. Samples of ore, slag and technical ceramics were collected for archaeometallurgical analysis. The technology of silver production is discussed in relation to the historical record, and elemental and lead isotope characterisation of ore and slag provides a basis for future provenance studies.

al-Radrad 的银生产：中世纪早期也门的矿石、矿渣和技术陶瓷的考古冶金分析

al-Jabali 锌铅银矿床位于也门萨那东北约 65 公里处，已被确定为古代/伊斯兰时期晚期银矿 al-Radrad 的所在地。从公元 10 世纪的阿拉伯地理学家 al-Hamdani 的记载中可以得知该矿的开采情况。al-Jabali 地区一直是地质和考古冶金调查的重点，发现了大量的冶金遗迹。收集矿石、矿渣和工业陶瓷样品用于考古冶金分析。结合历史记录讨论了白银生产技术，矿石和矿渣的元素和铅同位素表征为未来的物源研究提供了基础。
