The Eastern khoy metamorphic complex of NW Iran: A jurassic ophiolite or continuation of the Sanandaj-Sirjan zone?

, 2019
The Khoy complex in NW Iran has been widely regarded to consist of both Jurassic and Cretaceous ophiolites, but whereas the western Late Cretaceous ophiolite is unequivocal the nature of the eastern Jurassic body has been unclear. Field observations show

The Rattray Volcanics: Mid-Jurassic fissure volcanism in the UK Central North Sea

Journal of the Geological Society, 2018
The Middle Jurassic Rattray Volcanic Province is located at the triple junction of the North Sea continental rift system. It has previously been thought to be sourced from three large central volcanoes: the Glenn, Fisher Bank and Ivanhoe volcanic centres.

Ichnology of the Rhätsandstein in the Exter Formation (Triassic), Germany

Geological Journal, EarlyView.
Trace fossils from the Rhätsandstein of southern Germany record repeated colonization of high‐energy shallow‐marine substrates before the Triassic–Jurassic transition. The assemblage reflects environmental and preservational controls on ichnodiversity.

The rise and fall of a volcanic plateau: Landscape evolution at the fringes of the former Patagonian Ice Sheet, Meseta Chile Chico, central Patagonian Andes

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...

Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

Boreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...
