TITANITE OF THE VISHNEVOGORSKY ALKALINE COMPLEX (South Ural) [PDF]
Минералогия, 2019 Titanite CaTi(SiO4 )O is a common accessory mineral of alkaline rocks and pegmatites of the Vishnevogorsky alkaline complex, South Urals. It occurs in many magmatic assemblages, is found in some metasomatites, underwent deformation and recrystallization.

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)
Journal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.

Fluorite stability in silicic magmas. [PDF]
, 2004 Recent experimental evidence is used to assess the conditions under which fluorite forms an early crystallising phase in silicic magmas. Fluorite solubility primarily depends on the (Na + K)/Al balance in the coexisting silicic melt, reaching a minimum ...
