Based on the LA-ICP-MS U-Pb zircon ages of four metamorphic samples, we discuss geochronology and provenance Guadaiza nappe, an allochthonous unit that underlies Ronda peridotites (Betic Cordilleras, Spain). The nappe is composed Triassic marbles overlying a metapelitic sequence with schists migmatites. Zircons from quartzite interlayered yield maximum depositional age ca. 289 Ma supports age. ...

new structural, metamorphic, finite strain and kinematic vorticity data for granitic gneiss and metavolcano-sedimentary rocks of thetanumaharea in the arabian shield in saudi arabia reveal a history of deformation reflecting different tectonic regimes. kinematic analysis shows their relationship to the nappe contacts between the granitic gneiss and metavolcano-sedimentary rocks and explains the...

Pre-Mesozoic exotic crystalline blocks within the Outer Carpathian flysch have potential to unravel nature of their eroded basement source(s) and reconstruct Paleozoic–Precambrian history Protocarpathians. Strongly tectonized Campanian–Maastrichtian grey marls in Subsilesian Nappe Western Carpathians Poland contain a variety different lithology types, including granitoids andesites. Petrologica...
