Paleomagnetic ages of Miocene fluvio-lacustrine sediments in the Tianshui Basin, western China

► The Yanwan section of fluvial-lacustrine setting is dated to be 17.1-6.1 Ma. ► The ages of two fossil layers correspond to ∼8.0 Ma and ∼9.5 Ma in Yanwan section. ► High resolution paleoclimatic studies on this set of sediments is the next step.
