The Vendian Accretionary Event in the Southwestern Margin of the Siberian Craton

摘要

The present-day southwestern margin of the Siberian Craton is represented by its Early Precambrian inliers (Angara-Kan and Sayan) and Mesoproterozoic-Neoproterozoic marginal continental region that includes the Yenisei Range and Sayan areas (Fig. 1). The Early Precambrian evolution of structures of the Siberian Craton culminated with formation of the Early Protero-zoic Angara continental-margin foldbelt, intense intrusion of granitoids (1.87-1.84 Ga ago), and its general consolidation .
