Solduz Valley sites

Table I. Analytical Data for Sherds from the Solduz Valley Sites ...

Temporal Differences. The Solduz Valley pottery studied here covers the period from ca. 5500 B.C, to ca. 3550 B.C. The appreciable scatter in the NAA data presented in Table I raises the question of whether some of the scatter is the result of a temporal change in the chemistry of the clay sources used by potters at any or all of the three Solduz Valley sites. 

Small samplings of sherds from Tepe Gawra and Tell Ubaid indicate small, but probably significant, chemical differences between the clay sources at each site and between them and the ceramics of the Solduz Valley.
