Show moreThe stable isotope ratios of carbon (d13C), nitrogen (d15N) and sulphur (d34S) are measured to examine human diet, social stratification, mobility and animal husbandry practices. Three locations comprising four sites from the Yellow River Valleys of north China are investigated: Nancheng (Hebei Province), Xishan (Gansu Province), Liyi and Shanren (Shaanxi Province), and this work represents one of the largest and most detailed isotopic research projects ever conducted in China. This thesis focused on time periods and cultures that were previously underrepresented, in the literature such as the early Bronze/Iron Ages to the Qin Dynasty (221-206 BC). Further, this thesis found new evidence concerning dietary patterns, social stratification (or lack thereof), animal husbandry practices and human mobility during these formative pre-Qin Empire periods.
