Abstract

The Late Triassic was a time of widespread reef proliferation and carbonate platform expansion. Such trends are mainly documented in the Tethys realm. In this context, this work aims at improving our understanding of carbonate platforms of East Panthalassa during the Late Triassic. We investigate Upper Triassic carbonates of Wrangellia and Stikinia terranes, outcropping on Vancouver Island (Canada) and the Yukon (Canada) respectively. In order to characterise these deposits, the samples collected from several localities from both areas were investigated using a multidisciplinary approach including biostratigraphy, geochemistry and carbonate sedimentology. Our results further highlight the evolution of mid-oceanic shallow water environments of East Panthalassa domain during the Late Triassic. The results of this study are compared with the findings of coeval shallow water carbonates of the Tethys and West Panthalassa domains. This work provides important data to improve Early Mesozoic life evolution, paleoecology and paleogeographic reconstructions.
