Many of these ferrous artefacts show typological parallels with contemporary objects from Luristan in western Iran, and the possibility of their long-distance import from this well-known iron producing and using region has long been recognized. The present study uses material from Saruq al-Hadid and the contemporary site of Muweilah to explore the provenance of the earliest iron from southeastern Arabia, by (i) summarizing the evidence for the iron resources and technology in the region and adjacent areas; and (ii) compositionally analysing iron ores, iron slags and slag inclusions in artefacts from Saruq al-Hadid and Muweilah, alongside Iron Age ferrous artefacts from Iran, using OM, SEM-EDS, XRF, ICP-MS and LA-ICP-MS. Multivariate statistical analyses are used to explore these geochemical data, alongside a large dataset of ores and artefacts derived from existing geochemical and archaeological publications. The study identifies slag samples from Muweilah as originating from iron smithing activities, providing the first evidence for iron working of any kind in southeastern Arabia. Differences in the geochemical compositions of the material from Saruq al- Hadid and Muweilah and iron ores from the U.A.E. and Oman – particularly the distribution of rare earth ele- ments – suggest that Iron Age ferrous artefacts from southeastern Arabia were not smelted from locally-available iron ores. Rather, the study demonstrates geochemical similarities between southeastern Arabian iron objects, contemporary objects from Luristan, and ores of the Sanandaj-Sirjan metallogenic belt of Iran, suggesting that iron may have been imported, at least partially as complete objects, from this region. Multiple source deposits are indicated, however, and the possible contribution of iron from other regions of ancient Western Asia and neighbouring regions remains to be further explored. The research provides critical new information regarding the long-distance exchange contacts of southeastern Arabia society during the floruit of the early Iron Age, in the late second and early first millennia BCE. 1. Introduction In southeastern Arabia, the origins and earliest adoption of iron technology remain obscure. Several decades ago, an apparent dearth of ferrous remains at local Iron Age (c. 1250-300 BCE) sites prompted Lombard (1989) to describe this period in southeastern Arabia as “L’^age du fer sans fer” (an Iron Age without iron). Despite considerable archaeological excavation in the region in the 30 years since Lombard’s pioneering synthesis, with a few notable exceptions ferrous finds from local archaeological sites remain very rare. This local scarcity has been used to suggest that early iron artefacts recovered were obtained through exchange with neighbouring iron-producing regions such as Iran, and that indigenous iron smelting was not practiced in south- eastern Arabia until the subsequent Hellenistic Period, when ferrous remains and production residues become more common (e.g. Lombard, 1989; Magee, 1998; Yule and Weisgerber, 2015: 26). * Corresponding author.
