Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite

Terra Nova, Volume 38, Issue 2, Page 124-129, April 2026.
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone

Thermal behavior of muscovite sheet mica

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1963
The three spectral types of muscovite sheet mica, i.e., very pink ruby, light green, and dark green, were subjected to heat treatments at temperatures up to 600 °C. The changes in the apparent optic axial angle and in the absorption spectra (0.3 to 15 μ) were studied along with color.

Muscovites genetic types of gold ore and crystal-bearing deposits of the Urals

Литосфера, 2015
Mica of muscovite-fengite series are ones of the most important rock-forming minerals of metamorphic and metasomatic rocks in various metallic and nonmetallic deposits. The temperature and pressure significantly affects their composition, determining the
