摘要
Tell Halaf is the locality of the ancient Aramaic city of Guzana (c. 1000-800 BC) in Syria. The statues of Tell Halaf were made from monolithic basalt blocks, comprising massive as well as amygdaloidal types. However, the exact location of the original quarries was as yet unknown. Reconnaissance mapping and sampling concentrated on the four basaltic centres in the vicinity of Tell Halaf, covering both south-eastern Turkey and north-eastern Syria. In addition, basaltic artefacts from the two archaeological sites of Tell Beydar (c. 2700-2300 BC) and Djebelet el Beda (c. 2600-2350 BC) were investigated. All basalt samples were analysed for their bulk rock major and trace element compositions by X-ray fluorescence, ICP-MS analysis and the mineral chemistry of individual minerals by combined electron microprobe analysis and laser-ablation ICP-MS. The data show that basalt works of art from all three archaeological sites were derived from the Syrian basalt plateau of Ard esh-Sheikh, approximately 57 km south of Tell Halaf. Accordingly, this basalt quarry was actively exploited over a considerable time span of c. 1900 years. This study demonstrates that petrographic and geochemical investigations of basalt, combined with electron microprobe and laser-ablation ICP-MS analysis of minerals, are powerful tools to discriminate between possible sources of raw materials, especially if isotopic data yield unsatisfying results.
