Journal of Quaternary Science, EarlyView.ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

Progressive albitisation in the "Migmatite Creek" region, Weekeroo Inlier, Curnamona. [PDF]
, 2009 Albitisation is pervasive and intense in the Curnamona Province. Most FeO-Cu-Au-U-REE deposits are associated with sodic alteration or albitisation (alkaline alteration) worldwide.

SYNTHESIS OF ALBITE AT 210–240 °C
, 1966 High temperature albite was synthesized at 210 and 240 °C from a mixture of kaolinite, NaCl, and Na2CO3, each run lasting about 63 days. Identification was made by X-ray diffraction, supplemented by electron microscopy.

Microbial Respiration in Subtropical Urban Soils Depending on Vegetation Type
Land Degradation &Development, EarlyView.ABSTRACT Urban vegetation combines invasive and introduced species with native relics, whose litter is the primary source of organic matter inputs in urban soils. Plant litter quality regulates both organic carbon (C) storage and microbial activity in urban soils.

Mechanical and creep properties of granitic minerals of albite, biotite, and quartz at elevated temperature [PDF]
, 2023 Fundamental mechanical and creep behavior of minerals at elevated temperatures is relevant to many subsurface exploration and resource recovery processes, yet remains largely elusive.

Pressure induced elastic softening in framework aluminosilicate-albite (NaAlSi3O8)
, 2016 Albite (NaAlSi3O8) is an aluminosilicate mineral. Its crystal structure consists of 3-D framework of Al and Si tetrahedral units. We have used Density Functional Theory to investigate the high-pressure behavior of the crystal structure and how it affects

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.

A comparison betweenab initio calculated and measured Raman spectrum of triclinic albite (NaAlSi3O8) [PDF]
, 2015 Albite is one of the most common minerals in the Earth’s crust, and its polymorphs can be found in rocks with different cooling histories. The characteristic spectrum of vibration of the albite mineral reflects its structural Si/Al ordering.
