Effect of gypsum on potassium and iron release from phlogopite under laboratory conditions

Soil & Environment, 2018
This study estimated the effects of gypsum on the potassium and iron release rate from phlogopite under laboratory conditions. A randomized design with the factorial arrangement and three replications was utilized to run the current experiment ...

Valorization of Finnish mining tailings for use in the ceramics industry [PDF]

Bulletin of the Geological Society of Finland, 2018
The present study valorized Finnish mining tailings waste to identify opportunities for the use of ceramics technologies. On the basis of their mineralogical and chemical contents, the five selected tailings wastes represented felsic mining tailings (FMT)

Routes of phlogopite weathering by three fungal strains [PDF]

Fungal Biology, 2016
Fungi dissolve soil minerals by acidification and mechanical disruption. Dissolution may occur at the microscale (contact between fungus and mineral) and medium scale (entire mineral grains). Mineral weathering by fungi and other microorganisms is thought to be of significant global contribution, perhaps producing specific weathering signatures.

Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 155-179, March 2026.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

The crystal structure of phlogopite by neutron diffraction

Mineralogical Magazine, 1974
SummaryThe positions of all the atoms including hydrogen have been found by a partial three-dimensional single-crystal neutron-diffraction study in which about one-third of the reflections in the reciprocal sphere to 1·5 Å were measured. The hydroxyl group is perpendicular to the plane of the silicate sheets.

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Near-Infrared Spectroscopic Study of Biotite–Phlogopite (Mg# = 30~99): OH-Stretching Modes and Mg# Content Prediction Equation

Crystals
Biotite–phlogopite minerals are a complete Mg–Fe isomorphism series of phyllosilicates. A Fourier transform infrared spectroscopy (FTIR) and electron microprobe analysis (EMPA) were conducted on end-member phlogopite, Mg–biotite, and annite samples.
