TL;DR: Wang et al. as mentioned in this paper analyzed carbon isotope analysis of human, pig and dog bones, and radiocarbon dates from Neolithic sites, and compared them with black carbon content from palaeoenvironment records in northern China, in order to explore the temporal-spatial intensification and expansion of millet-based agriculture in the area and its possible impact on environment.

TL;DR: In this article, X-ray fluorescence (XRF) measurement and principal component analysis (PCA) were conducted on heavy metal element (Cu, Ni, Pb, Zn, Cr and As) concentrations (HMEC) of natural and anthropogenic sediment samples systematically collected from 22 late Neolithic-Bronze Age sites in Hexi corridor to explore the potential for subcontinental-wide changes in soil geochemistry.

TL;DR: In this paper, the authors analyzed the Cu concentrations of samples collected within cultural layers of anthropogenic sediments from 17 Late Neolithic and Bronze Age sites located within the Hexi Corridor.

TL;DR: In this paper, a refined radiocarbon (14C) chronology is presented to resolve the timing of human occupation and cultural evolution in the Hexi Corridor of northwest China, which was one of the earliest centers for long-distance culture exchange in the prehistoric world.

TL;DR: The Gansu-Qinghai region lies in the key position for trans-Eurasian cultural exchange, and hence investigations of the history of agricultural development in this region are significant for under-served communities as discussed by the authors.
