Abstract

Abstract

Naxing Formation of Upper Carboniferous in Dingri and Dingjie, Tibet, is a terrigeneous clastic deposit with huge thickness. Gravity flow facies including collapse, debris flow and turbite facies are distinguished firstly in the middle part of the formation. The sedimentary facies and source analysis based on sediment composition and geochemical characteristics reveals that the environment of the area in Late Carboniferous used to be a small fault basin related with the Hercynian extensional movement, and that an extensional unconformity is situated between the gravity flow facies and shore-shelf facies in the lower part of Naxing Formation.
