Gorstian palaeoposition and geotectonic setting of Suchomasty Volcanic Centre (Silurian, Prague Basin, Teplá-Barrandian Unit, Bohemian Massif)

Listed in DataCite

A multidisciplinary palaeomagnetic, whole-rock geochemical and volcanological study was carried out in Gorstian deposits of the Suchomasty Volcanic Centre in the western segment of the Prague Basin (Teplá-Barrandian Unit, Bohemian Massif).

Description

Phreato-Strombolian eruptions of alkali basalts, transitional between enriched mid-ocean rift basalt and ocean-island basalt, associated with effusions of lava flows within the lower–middle Scanicus chimaera graptolite Biozone at the Vinařice locality, yield a mean palaeomagnetic direction that allows for computation of a palaeolatitude of 24.4°S. Present data support that the Prague Basin was a continental rift basin, situated on presumed Perunica microplate.

The Perunica microplate drifted at southern subtropical palaeolatitudes of 24.4° in Gorstian time and experienced either 170° counter-clockwise or 190° clockwise rotation during the Variscan Orogeny.
