Neoproterozoic to early Cambrian Franciscan-type mélanges in the Teplá-Barrandian unit, Bohemian Massif: Evidence of modern-style accretionary processes along the Cadomian active margin of Gondwana?

Popis výsledku v původním jazyce

Mélanges have been reported from a variety of modern tectonic settings and are a hallmark of the Franciscan-type subduction-accretion complexes. In the Precambrian, however, well documented examples of melanges become extremely scarce. This paper describes in detail Neoproterozoic to early Cambrian melanges recently recognized in the Cadomian basement of the Teplá-Barrandian unit, Bohemian Massif. The melanges are of sedimentary and tectonic origin and include voluminous successions of graywackes interpreted to represent mass-transport deposits presumably along the upper slope of an accretionary wedge. The clast compositions indicate multiple episodes of mixing of terrigenous arc-derived and deep-water (?pelagic) material. Moreover, abundant bodies of(meta-)basalts, interpreted as dismembered seamounts or pillow volcanoes, were emplaced tectonically into various structural levels of this sedimentary melange by two different mechanisms. At an upper level, the irregular to elongated bod
