Abstract

Abstract

The Naij Tal Group, an important stratigraphic unit, is of great significance to reconstruction of the geological evolution of the East Kunlun orogenic belt during the Early Paleozoic, but divergent opinions have been proposed about its tectonic environment. Based on close geological survey, a geochemical analysis has been made on the clastic rocks in the OrdovicianSilurian Naij Tal Group in East Kunlun orogenic belt, and the results demonstrate that this group was formed in passive continental margin, rather than in fore-arc basin on active continental margin. The study provides geochemical evidence for the study of early Paleozoic tectonic evolution in east Kunlun orogenic belt.
