Multidisciplinary Study of Burnt Deposits at Surungur, Fergana Valley, Southern Kyrgyzstan

Abstract

Burnt deposits are an important source of information on ancient lifestyles, providing the possibility of reconstructing the size, intensity of use, and functions of fi replaces at prehistoric settlements, and to assess fuel sources. We outline the results of a multidisciplinary study of fi replaces and their contexts at Surungur-a stratifi ed site in the Fergana Valley, in southern Kyrgyzstan. Sixteen samples from ash lenses and intermediate deposits were studied by rock-magnetism, gas chromatography mass spectrometry (GC-MS), and X-ray fl uorescence (XRF). The rock-magnetic analysis suggests that the origin of all samples from ash lenses was anthropogenic. Types of fuel were reconstructed. At the initial stage (Early Holocene), the encompassing deposits likely resulted from short-term occupation, and fuel consisted of wood and grass/ dung. In the Middle Holocene, occupation became more long-term, as evidenced by maximal heating temperatures and high concentration of fi replaces. During the Late Holocene, habitation intensity on the platform under the stone ledge remained the same, but heating was less intense. Wood and grass/dung were used as fuel at all stages, suggesting that wood was available in the region throughout the Holocene.
