Transition from island-arc to passive setting on the continental margin of Gondwana: U-Pb zircon dating of Neoproterozoic metaconglomerates from the SE margin of the Tepla-Barrandian Unit, Bohemian Massif

Abstract

Geochemical data combined with radiometric dating of pebbles from Neoproterozoic metaconlgomerates were used to characterize geotectonic settings at the Neoproterozoic - Cambrian boundary
