The basement of the Cretaceous-Eogene Poyang Basin was an activated Indosinian intracontinental orogen in Late Mesozoic, with the structural line being same to the Indosinian one (the NEE-striking), and the thrusting controlled by the Yanshanian orogeny (towards the southeast). The thrusting in Jiangxi occurred in Late Jurassic and Early Cretaceous, and resulted in the Proterozoic outcropping in central rise of the Poyang Basin.
