A Bronze Age culture of the Gansu and Qinghai provinces of China, dated c. 1500-1000 BC (a radiocarbon test on one artefact produced a date around 1000 BC), part of the upper Yellow River Bronze Age sequence alongside Qijia and Siwa.
Succeeded regionally by later upper-Yellow-River Bronze Age cultures (e.g. Kayue, starting c. 900 BC, verified below as outside this window).
Survey of early Chinese archaeology; covers the Gansu-Qinghai Bronze Age cultures including Xindian.
