Role of XRF in the restoration of a prominent architectural monument at the site of Mleiha

The fort at Mleiha is one of the most well known archaeological sites of its period (3rd c. BC to 3rd c. AD) in the United Arab Emirates and has provided much valuable information. The period of its construction and use coincided with the Parthian period, during which there were extensive commercial contacts between the UAE and Mediterranean cities, Egypt, Mesopotamia, Southwest Iran, Pakistan, East Africa, and the southern Arabian Peninsula. It was restored using local materials, and traditional construction methods. The objective of this study was to utilize XRF techniques for the identification of the elemental composition of building material used to construct an archaeological fort, and to compare it to composition of the restoration material. Results of the study show strong correlation between the original fort building material and those used for restoration.
