Upper Devonian pelecypods of the New York Chemung stage [PDF]
, 1962 The Upper Devonian rocks of New York and northern Pennsylvania provide perhaps the world\u27s best opportunity for understanding the late Devonian pelecypods, because only in this region, among all well-known Devonian exposures, was deposition relatively

Journal of Quaternary Science, EarlyView.ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Devonian Sandstone Lithostratigraphy, Northern Arkansas [PDF]
, 1977 Two areas of Devonian sandstone development may be recognized in northern Arkansas. In northwestern Arkansas, the Clifty Formation comprises a massively bedded, super mature quartz arenite of Middle Devonian age overlain by thinner bedded, phosphatic ...

Upper Devonian lithostratigraphy of Belgium
Geologica BelgicaThe lithostratigraphic scale of Belgium, which is the cradle of several global Devonian stages, has been revised after completion of the update of the Geological Map of Wallonia (Carte géologique de Wallonie) at a scale of 1/25,000 and recent stratigraphic and sedimentological research.

A talus rock glacier in Nantlle Valley, North Wales
Journal of Quaternary Science, EarlyView.ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Journal of Quaternary Science, EarlyView.ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Upper Silurian and Lower Devonian conodonts from the Monte Cocco II section (Carnic Alps, Italy) [PDF]
, 2009 The upper Silurian-Lower Devonian Monte Cocco II section, located in the eastern part of the Carnic Alps, yielded abundant conodonts from five conodont biozones (snajdri, crispa, eosteinhornensis s.l., detortus and woschmidti).

Archaeometry, EarlyView.ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for
