  1. Biochronology and magnetostratigraphy of the Pliocene Panaca Formation, southeast Nevada

    … in the Panaca Formation is interpolated from magnetostratigraphy and is considered as the age of the Hemphillian-Blancan boundary. The magnetostratigraphy of the Panaca Formation in Meadow Valley is established based on four sections in the basin. The ash in the Rodent Hill section was dated …

  2. The magnetostratigraphy of Coniacian-Late Campanian chalk sequences of Southern England

    Results from a detailed palaeomagnetic study of the Late Cretaceous sequences of Culver Cliff and Scratchell's Bay (Isle of Wight) and Seaford Head, East Sussex are presented. The sections range in age from Latest Turonian to early Late Campanian and consist of white chalk with flints. Hand samples …

  5. FROM EAST TO NORTH-WEST AFRICA: MAGNETOCHRONOLOGY OF THE OLDEST AFRICAN ACHEULEAN SITES

    … are presented the chronologies, obtained through magnetostratigraphy, of two key sites of archaeological and paleoanthropological interest, Melka Kunture (Upper Awas Valley, Ethiopia) and Thomas Quarry I (Casablanca, Morocco). These sites of Pleistocene age document the emergence and developments …

    … of two sedimentary sections is performed using magnetostratigraphy, apatite fission-track and luminescence dating. Provenance analysis using zircon and apatite U-Pb dating allows the reconstruction of the Miocene-Quaternary paleo-drainage of the Brahmaputra River and the documentation of the …

  8. The roof of the cyclades : a structural, stratigraphic, and paleomagnetic study of Neogene extensional tectonics in Central Greece

    … I date the basin fill using a combination of magnetostratigraphy and U/Pb zircon geochronometry. Through detailed mapping of the spatial variation in sedimentary facies within the basin, I relate the record of sedimentation to Middle Miocene extensional exhumation of the metamorphic core …

    … these biostratigraphic datums, combined with a magnetostratigraphy being developed for the section, form an age framework for the sedimentary succession exposed in the Wanganui River valley between Tieke and Parakino. The apparently diachronous nature of the datums traditionally tied to the …

  11. Fluvial sedimentation in continental half-graben basins

    The stratigraphic architecture of intracontinental rift basins is defined by a dynamic relationship between depositional belts associated with the basin floor and flanking tributary streams on the piedmont. Spatiotemporal distributions of these deposits are sensitive to basin geometry, subsidence …
