Absorption of Neptunium to Muscovite With Different Particle Sizes [PDF]

open access: yesHe huaxue yu fangshe huaxue
Neptunium is one of long-life radioelements, whose speciation in different condition of underground water and soil type, including the adsorption characteristics and adsorption mechanism on some soils, is a critical field. The adsorption behavior of Np(Ⅴ)

Occurrence and mineralogy of the margarite- and muscovite-bearing pseudomorphs after topaz in the Juurakko pegmatite, Orivesi, southern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1988
Margarite- and muscovite-bearing pseudomorphs after topaz are described from the Juurakko pegmatite dyke, Orivesi, southern Finland. A supercritical vapour phase rich in calcium and alkalies caused alteration of topaz and some other silicates during ...

Detrital Mica Composition Quantitatively Indicates the Sediment Provenance along the Subei Coast to the Yangtze Estuary

open access: yesApplied Sciences, 2022
The influence of large rivers on the Subei littoral plain area requires more research than the results that have been available up to now. Thus, specific diagnostic indices of detrital mica are successfully applied for the first time to identify the ...

Composites Based on Post-Industrial Wood Plastic Waste and Ultrasonic Treated Muscovite [PDF]

open access: yesMaterials Research, 2023
In this work muscovite was ultrasonically treated to obtain composites with post-industrial wood plastic residues. The muscovite was ultrasonicated for 30 or 60 min and mixed with the polymeric matrix at a constant level of 15% (weight percentage).

Potassium at the Origins of Life: Did Biology Emerge from Biotite in Micaceous Clay?

open access: yesLife, 2022
Intracellular potassium concentrations, [K+], are high in all types of living cells, but the origins of this K+ are unknown. The simplest hypothesis is that life emerged in an environment that was high in K+.

Petrology and geochronology of "muscovite age standard" B4M [PDF]

open access: yes, 2014
Muscovite B4M, distributed in 1961 as an age standard, was ground under ethanol. Five grain size fractions were obtained and characterized by X-ray diffraction. They display a mixing trend between a phengitic (enriched in the fraction 20 µm).

Chemical zoning of muscovite megacrystal from the Brazilian Pegmatite Province

open access: yesAnais da Academia Brasileira de Ciências, 2007
Macroscopically homogenous muscovite plate from the Cruzeiro pegmatite, located in the Eastern Pegmatite Province in Minas Gerais, may show complex distribution patterns of some trace elements. In geochronological and petrological studies, as for example
