Land Degradation &Development, EarlyView.ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

b>Energy requirement for firing porcelain
Bulletin of the Chemical Society of Ethiopia, 2004 Results from studies on the ternary system Ribaué kaolin–Carapira feldspar– Marracuene quartz sands were used to test a procedure that we developed for calculation of the energy requirement for firing porcelain.

Materials and Corrosion, EarlyView.This study examines corrosion of copper and cast iron as candidate canister materials for high‐level radioactive waste disposal in contact with bentonite suspension. The influence of three electrolyte compositions on corrosion behavior under repository‐relevant conditions is assessed.

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Centennial- to millennial-scale hard rock erosion rates deduced from luminescence-depth profiles [PDF]
, 2018 The measurement of erosion and weathering rates in different geomorphic settings and over diverse temporal and spatial scales is fundamental to the quantification of rates and patterns of earth surface processes. A knowledge of the rates of these surface

Responses of ectomycorrhizal fungi to mineral substrates [PDF]
, 2003 Boreal forest soils are complex, heterogeneous growth substrates where organic and mineral components provide nutrient resources for soil organisms and plants. Mineral nutrients are cycled between living and dead organic components of the forest soil and

Lumineszenz-Datierung der Löss-Paläoboden-Sequenz in der Kiesgrube Gaul/Weilbach, Südhessen [PDF]
, 2011 A thick Middle and Late Pleistocene loess/palaeosol sequence is exposed at the gravel quarry Gaul located east of Weilbach in the southern foreland of the Taunus Mountains. The loess/palaeosol sequence correlates to the last three glacial cycles.

Can Ice-Like Structures Form on Non-Ice-Like Substrates? The Example of the K-feldspar Microcline
The journal of physical chemistry. C, Nanomaterials and interfaces, 2016 Feldspar minerals are the most common rock formers in Earth’s crust. As such they play an important role in subjects ranging from geology to climate science. An atomistic understanding of the feldspar structure and its interaction with water is therefore
