Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England

Journal of Quaternary Science, EarlyView.
ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,

A General Model for the Permeability of Magma Mush

Geochemistry, Geophysics, Geosystems
Percolation through magma mush is a key transport mechanism for melts in the crust and is influenced by the permeability of the crystal framework. Existing models for mush permeability do not account for the range of microstructures that can evolve as ...

Lateglacial and Holocene mountain glacier fluctuations near Cape Farewell South Greenland inferred from 10Be moraine dating

Journal of Quaternary Science, EarlyView.
ABSTRACT We report 43 new 10Be exposure ages and six 26Al/10Be measurements from replicates from a small piedmont mountain glacier located at Cape Farewell (south Greenland) and temperature anomalies estimated from equilibrium‐line altitude (ELA) changes derived from 3D glacier reconstruction carried out using the ‘GlaRe’ toolbox.

Climate and catchment influence the postglacial succession of three lakes in south‐central Baffin Island (Nunavut), Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding postglacial ontogeny in Arctic lakes helps contextualize modern‐day climatic change. We used sediment cores to characterize ecological succession in three south‐central Baffin Island lakes from deglaciation (c. 7–8k cal a BP) to present.

Raman Study of the Slobodka Ordinary Chondrite

Journal of Raman Spectroscopy, EarlyView.
The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.
