Abstract

The Cretaceous non-marine deposits play an important role in the history of formation and evolution of Earth’s crust in northern territory of Vietnam. According to analyzing results of material composition and depositional environments, these deposits can be divided into three lithofacies assemblages, such as proluvial-deluvial, fluviatile and lacustrine lithofacies. These Cretaceous non-marine sequences in the North of Vietnam indicate a typically continental hot and dry palaeoclimatic regime.

Highlights

  • The Cretaceous non-marine deposits play an important role in the history of formation and evolution of Earth’s crust in northern territory of Vietnam

  • The Cretaceous non-marine sequences are all located in almost structural zones in northern territory of Vietnam in the various forms, depending on the influence of regional tectonic and erosional regimes

  • With a stratigraphical discontinuity, the Cretaceous non-marine deposits (350 - 1400 m) in northern Vietnam are characterized by two types of sections: 1) They unconformably overlie on the Lower and Middle Jurassic

Summary

Introduction

The Cretaceous non-marine sequences are all located in almost structural zones in northern territory of Vietnam in the various forms, depending on the influence of regional tectonic and erosional regimes. Three lithofacies assemblages were distinguished and many palaeoclimatic signals can be reflected
