Department of Geology) ; Bea, Fernando (Universidad de Granada. Departamento de Mineralogía y Petrología)
The Ghorveh-Dehgolan plutons of the northern Sanandaj-Sirjan Zone, Zagros Orogen, comprise seven composite intrusive bodies that were generated during northeastward subduction of Neotethys beneath the Iranian sector of the Eurasian plate. [...]

17 p, 1.8 MB Geochemistry and provenance of the Lower Siwaliks from southwestern Kohat, western Himalayan Foreland Basin, NW Pakistan / Ullah, K. (University of Peshawar (Pakistan). National Center of Excellence in Geology) ; Arif, M. (CIIT Department of Earth Sciences (Pakistan)) ; Tahir Shah, M. (University of Peshawar (Pakistan). National Center of Excellence in Geology)
Equivalent to the Lower Siwalik Group, the Late Miocene Chinji Formation in Pakistan consists of interbedded in-channel sandstone (SSt) and overbank mudstone (MSt) sequences. Twelve sandstone and sixteen mudstone samples from three different sections of the formation in southwestern Kohat, NW Pakistan were analyzed for major elements and selected trace elements. [...]

6 p, 3.0 MB First known fossil bird tracks (Pleistocene) on San Salvador island, Bahamas / Martin, A. J. (Emory University (Atlanta, Estats Units d'Amèrica). Department of Environmental Sciences) ; Whitten, M. J. (Emory University (Atlanta, Estats Units d'Amèrica). Department of Environmental Sciences)
Two avian footprints discovered in the Grotto Beach Formation (Pleistocene) of San Salvador Island (Bahamas) are the first known vertebrate trace fossils on this well-studied island. The trace fossils, preserved as beddingplane impressions in an oolitic-bioclastic grainstone, match the size and form of tracks made by modern gulls. [...]

6 p, 803.5 KB Reply to the comment by Michard et al. on "Evidence of extensional metamorphism associated to Cretaceous rifting of the North-Maghrebian passive margin : The Tanger-Ketama Unit (External Rif, northern Morocco) by Vázquez et al., Geologica Acta 11 (2013), 277-293" / Vázquez, M. (Universidad de Chile. Andean Geothermal Center of Excellence (CEGA)) ; Asebriy, L. (Université Mohammed V. Institut Scientifique) ; Azdimousa, A. (Université Mohammed I. Laboratoire LGA) ; Jabaloy, A. (Universidad de Granada. Departamento de Geodinámica) ; Booth-Rea, G. (Universidad de Granada. Departamento de Geodinámica) ; Barbero, L. (Universidad de Cádiz. Departamento de Ciencias de la Tierra) ; Mellini, Marcello (Università di Siena. Dipartimento di Scienze della Terra) ; González-Lodeiro, F. (Universidad de Granada. Departamento de Geodinámica)
Michard et al. (this issue) commented on certain aspects of the Alpine metamorphism and structural evolution of the Rif belt (Morocco) that were briefly noted in Vázquez et al. (2013). In particular, they criticize our interpretation of an extensional setting during the main metamorphic recrystallization of the Tanger-Ketama Unit that we considered related to slaty cleavage (S1) parallel to the lithological layering generated during the Cretaceous.
