Геодинамика и тектонофизика, 2015 The tectonic and paleogeographic evolution of the Ural-Mongol belt between the cratons of Baltica, Siberia, and Tarim is the key to the formation of the Eurasian supercontinent during Paleozoic time, but the views on this complicated process remain very ...

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 ...

G2‐PASE: A Novel, Rapid, and Reliable Measure of Plaque Psoriasis Severity
JEADV Clinical Practice, EarlyView.ABSTRACT Background The Psoriasis Area and Severity Index (PASI), a composite measure of plaque psoriasis disease severity, is commonly used to determine treatment eligibility and response, but is time consuming for every‐day clinical use. The Gulliver‐Gestalt‐Psoriasis Area Severity Estimate (G2‐PASE) was developed to approximate PASI scores using ...

Acta Palaeontologica Polonica, 2023 Fossils of Devonian ammonoids are abundant and well-preserved in the Anti-Atlas of Morocco; as such they provide an invaluable record of regional morphological disparity changes (diversity of shapes) that characterise the first steps of ammonoid ...

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Middle Devonian lithostratigraphy of Belgium
Geologica BelgicaThe revision of the lithostratigraphic scale of southern Belgium, based on the revised geological map of Wallonia and recent stratigraphic and sedimentological works, has led to the re-definition of 63 lithostratigraphic units for the Middle Devonian Series.

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference
