Structure, emplacement, and tectonic setting of Late Devonian granitoid plutons in the Tepla-Barrandian unit, Bohemian Massif
Original language description
The Štěnovice and Čistá granodiorite-tonalite plutons are small (similar to 27 and similar to 38 km(2), respectively) intrusions that are largely discordant to regional ductile structures in the center of the upper-crustal Tepla-Barrandian unit, BohemianMassif. Their whole-rock and trace-element compositions are consistent with medium-K calc-alkaline magma, generated above a subducted slab in a continental margin arc setting. The U-Pb zircon age of the Štěnovice pluton, newly determined at 375 +/- A 2Ma using the laser ablation ICP-MS technique, is within the error of the previously published Pb-Pb age of 373 +/- A 1 Ma for the Čista pluton. The two plutons also share other characteristics that are typical of concentrically expanded plutons (CEPs), such as elliptical cross-section in plan view, steep contacts, inferred downward-narrowing conical shape, faint normal zoning, and margin-parallel magmatic foliation decoupled from the regional host-rock structures.
