STRUCTURAL FEATURES AND EVOLUTION OF THE NADANHADA TERRANE

The study of terranes has already become an important subject in research of the Circum-Pacific continental margin. This paper discusses proper understanding of the terrane conception and identifies existence of the Nadanhada terrane according to its difference from the neighbouring massifs in terms of evolutionary history, tectonic background, and deformation features, and to the fault-contact relation between them; analyzes the paleogeographic position variation of the Nadanhada terrane during the Triassic to late Jurassic and the period when the terrane was attached to the ancient continental marging; finally discusses the consequential effects of theterrane accretion from the observed tectonic events after terrane collage.
