The following is a preliminary report on the results achieved during approximately six weeks' archaeological fieldwork in north-eastern Iran in July and August 1963. The primary objective was to explore the area for traces of the local Upper Pleistocene cultural sequence, and in particular to establish if possible the date and character of the local Upper Palaeolithic. In the event no traces of Upper Palaeolithic were obtained. However, a start was made towards defining the problem by the discovery of two well-stratified deposits, the one yielding a Middle Palaeolithic (Mousterian) industry with distinctive regional affinities, and the other an early Post-glacial Mesolithic industry. Reliable samples were obtained for defining the statistical properties of both, together with carbon samples, traces of vertebrate fauna, and some other climatic data.

Representative collections were lodged with the Musée Iran Bastan at Teheran; and the expedition's share is to be offered in part to the Museum of Archaeology and Ethnology in Cambridge and in part to the British Museum. The expedition was financed mainly by a grant from the British Academy, supplemented by further grants from the Crowther-Beynon Fund and the British Museum.
