Abstract

Abstract

There is a wide distribution of thick loessal sediment around Qiaojia in the Jinshajiang River valley, especially near the Huatan area, Ningnan county, Sichuan province on the left bank.The sediment is very thick, rich in calcareous concretions, and with no clear bedding.A detailed magnetostratigraphic study combined with thermoluminescence dating of seven sections of the sediment shows that it was deposited during the late Brunhes normal epoch, and has a geologic age of Late Pleistocene to Holocene.
