SEDIMENTARY FACIES AND SEQUENCES OF JURASSIC IN EASTERN JUNGGAR BASIN

Abstract

Abstract: According to sedimentary environment and facies, this paper further classified and correlated the Jurassic in eastern Junggar basin by using sequence stratigraphy method, and compreben-sively analysed sedimentary facies and sequence of study area by applying geologic, logging and seismic methods. It is considered that Jurassic is a set of termigeneous clastic sediments controlled by tectonic and climate conditions,which is divided into humid and arid type based on sedimentary characteristics; and also divided into northern genue slope type and southem steep slope type based on low- wter level system tract .

Key words: Junggar basin, Jurassic, Sedimentary facies, Sequence stratigraphy, Stratigaphic sequence, Seismic facies
