All rights reserved A geochemical study of bituminous mixtures from Failaka and Umm an-Namel (Kuwait), from the Early Dilmun to the Early Islamic period This paper is the last in a series presenting geochemical analyses of fragments Jacques Connan1 and Robert of bituminous mixtures excavated from archaeological sites in Kuwait. The Carter2 first was devoted to bituminous boat remains from the Ubaid-related 1Laboratoire de Ge´ochimie Neolithic site of H3, As-Sabiyah, while the second dealt with bituminous Bioorganique, UMR 7509, amalgams from the Partho-Sasanian site of cAkkaz, a former island now CNRS, 25 rue Becquerel, joined to the south side of Kuwait Bay.

It can be confirmed that the recipes used in the preparation of these bituminous amalgams comply with those traditionally used in antiquity, as seen at many sites in Mesopotamia and the Gulf. Analysis of the soluble organic matter, and especially its ‘‘saturates’’ fraction, provided sterane and terpane distributions and the measurement of diagnostic molecular ratios.
