Human migration into Europe during the late Early Pleistocene climate transition [PDF]

open access: yes, 2010
A critical assesment of the available magnetostratigraphic and/or radiometric age constraints on key sites bearing hominin remains and/or lithic industries from southern Europe (Italy, France, Spain) leads us to propose that the main window of early ...

Integrated stratigraphy and astrochronology of the Messinian GSSP at Oued Akrech (Atlantic Morocco) [PDF]

open access: yes, 2000
A much improved high-resolution integrated stratigraphy (calcareous plankton biostratigraphy, magnetostratigraphy, cyclostratigraphy) is presented for the classic section of Oued Akrech (Atlantic Morocco) straddling the Tortonian^Messinian boundary ...

Ammonites and magnetostratigraphy of the Berriasian–Valanginian boundary deposits from eastern Crimea

open access: yesGeologica Carpathica, 2017
Euthymi, Crassicostatum and Callisto ammonite subzones, correlable with Paramimounum, Picteti, and Alpillensis subzones and probably with the Late Berriasian Otopeta Subzone of the Boissieri Standard Zone have been recognized in calcareous clays of the ...

Magnetobiostratigraphy of the Spathian to Anisian (Lower to Middle Triassic) Kçira section, Albania [PDF]

open access: yes, 1996
Magnetobiostratigraphic data are presented from three Early/Middle Triassic Han-Bulog Limestone successions from Kçira, northern Albania. A total of 206 standard palaeomagnetic samples were obtained for thermal demagnetization and statisticalanalysis ...

The Jurassic of Denmark and Greenland: The Upper Jurassic of Europe: its subdivision and correlation [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2003
In the last 40 years, the stratigraphy of the Upper Jurassic of Europe has received much attention and considerable revision; much of the impetus behind this endeavour has stemmed from the work of the International Subcommission on Jurassic Stratigraphy.

Geomagnetic Field Behavior at High Latitudes from a Paleomagnetic Record from Eltanin Core 27-21 in the Ross Sea Sector, Antarctica [PDF]

open access: yes, 2007
We present a high-resolution paleomagnetic record from 682 discrete samples from Eltanin 27-21 (69.03°S 179.83°E), a 16-meter long piston core recovered in 1968 at a water depth of 3456 meters by the USNS Eltanin as part of Operation Deep Freeze.

Paleomagnetic constraints on the age of the Botucatu Formation in Rio Grande do Sul, southern Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2006
Paleomagnetic and rockmagnetic data are reported for the aeolian Botucatu Formation, in the southern Brazilian State of Rio Grande do Sul. Oriented samples were taken from a section located between the cities of Jaguari and Santiago.
