Geography comments: Site is one of many located "in the eastern Gonghe Basin of the north-eastern Tibetan Plateau, all located above 2600m asl"
"Ten charred millet seeds were selected from three cultural layers and two ash pits... for AMS radiocarbon dating"
Layer 1 is undated (the three cultural layers being Layers 2-4)
The youngest date given for Layer 2 is "2090±105 cal BC (at 95.4% confidence)" which corresponds to an uncalibrated date of "3700±25 BP"
Layer 1 is not any older than this date

Environment
Lithology: not described
Taphonomic context: human accumulation
Archaeology: bone tools,burials,ceramics,hearths,stone tools,other artifacts
Habitat comments: Site was "first investigated in 1982 by the Qinghai Provincial Institute of Cultural Relics and Archaeology... yielded two burials and a pottery kiln" Further excavations conducted between 1994 and 1996 "uncovered a total of 341 tombs, 18 ash pits and 18 sacrificial pits, and over 30 000 artefacts, including ceramic sherds, lithics, animal remains and bone objects"
Methods
Life forms: rodents,ungulates
Sampling methods: quarry,screenwash
Sample size: 5 specimens
Sampling comments: "In 2015, we excavated a small trench measuring 4 × 4m at the Zongri type-site, identifying three distinct cultural layers"
"Systematic archaeobotanical and zooarchaeological sampling was conducted for all features and layers encountered in the trench: 92 soil samples were taken... which contained 4150 charred plant seeds and 3132 fragments of animal bone"
"fragments of animal bones were floated from soil samples"
