Abstract

Abstract:

Jijitan site, which is located in Nihewan Basin, Heibei Province in northern China, was discovered in the 1980s. Three localities were documented, among which Locality 2 (T2) yielded the most specimens, including lithic artifacts and animal bones. Due to modern dam construction, Locality 2 was totally destroyed and no archaeological deposits preserved. Localities 1 and 3 are partly preserved, although badly destroyed by natural agencies and modern human activities. In our project, Localities 1 and 3 are re-examined, and a high density of lithic artifacts unearthed. OSL and Radiocarbon dating indicate that the anthropogenic deposits of Localities 1 and 3 were accumulated from about 16000 years ago to the early Holocene, which overlaps with the Hutouliang site complex on the opposite side of the Sanggan River. This result indicates that, during this time period, ancient humans occupied a vast area along the Sanggan River, and the population was fairly large.

Key words: Nihewan Basin, Upper Paleolithic, Jijitan, Chronology
