Two blocks of asphalt (bitumen) were found with archaeological artifacts in Tell Ghanem al-Ali by Dr. Tomoyasu Kiuchi, the University of Tokyo. The asphalt has been used as a waterproofing agent and/or adhesive material. It is interesting to know where these asphalt blocks were collected and transported from. One of the possible methods to discriminate the asphalt from various places is to compare its organic compound. Asphalt contains various organic compounds with straight chain and cyclic chain. The isotope ratios of ^<13>C/^<12>C of the compound also differ from sample to sample. These are effective methods to discriminate the asphalt. We collected the natural asphalt samples from two places in the area. The one place is the asphalt mine in the Bishri Mountains. This mine locates far from Euphrates, but produces asphalt with good quality. We sampled three asphalt (T09030901~3) from natural stream bed. We also surveyed work faces of the asphalt mine in detail and sampled asphalt at the mining outcrop from top to bottom layers (T09030904~07). The other sampling place is in the 3rd terrace at Zor Shammar, 5 km west of Tell Ghanem al-Ali. The asphalt formation is small and has about 50 cm thickness. The asphalt had permeated into gravel bed. One asphalt sample (T09030908) was collected from there. These naturally occurring asphalts and two asphalt samples from Tell Ghanem al-Ali were examined their organic compound, elemental compositions and isotopic ratio at Nagoya Univer sity. Any clear chemical comparison among natural asphalts and two archeological asphalts could not found. One of the possible reason is in chemical alteration of organic compounds during handicraft processing with heat in ancient period.
