SYNTAXY OF TITANITE, AEGIRINE AND ECKERMANNITE IN ALKALI SYENITE PEGMATITES OF THE VISHNEVYE MOUNTAINS (SOUTH URALS) [PDF]
Минералогия, 2016 Crystallographic orientation of titanite intergrowths with aegirine and eckermannite was found in alkali syenite pegmatites of the Vishnevye Mountains: the titanite face ( 1 11) is parallel to pyroxene and amphibole face (010) and the titanite face (110) is parallel to pyroxene face (110).

NEW DATA ON PYROCHLORE OF ALKALI PEGMATITES AND ORE ZONES OF THE VISHNEVYE MOUNTAINS (SOUTHERN URALS) [PDF]
Минералогия, 2018 The minerals of the pyrochlore group are abundant in rocks of the Vishnevogorsk alkaline complex – miaskites, mica rocks, carbonatites, and their pegmatites. Several generations of pyrochlore can be found in complex pegmatite bodies. According to the current nomenclature, fluorcalciopyrochlore, oxycalciopyrochlore, oxynatropyrochlore, oxycenopyrochlore,

POLYCHROME CANCRINITE–VISHNEVITE OF ALKALI PEGMATITES OF THE KUROCHKIN LOG OCCURRENCE, VISHNEVYE MOUNTAINS OF THE URALS [PDF]
Минералогия, 2018 Polychrome cancrinite–vishnevite crystal was found in alkali nepheline-feldspar pegmatites of the Kurochkin Log occurrence from the Vishnevye Mountains in the Southern Urals. A crystal 15 mm in size exhibits a gradual transition from early yellow zones of S-bearing cancrinite (Na5.32Ca0.89□)6.21(Al6.07Si5.93O24)(CO3)0.59(SO4)0.41• 3H2O to late blue ...

CONCENTRIC-ZONAL AGGREGATE OF REE MINERALS IN FELDSPAR PEGMATITE OF THE VISHNEVYE MOUNTAINS, SOUTH URALS [PDF]
Минералогия, 2019 A concentric-zonal texture of mineral aggregate observed in alkali pegmatite of the Vishnevye Mountains was formed as a result of melt-fluid crystallization in a closed system. At the first stage, rare large monazite crystals were crystallized creating wave concentration fields. Allanite-(Ce), bastnäsite-(Ce), chevkinite-(Ce), thoroaeschinite, apatite-(

MINERALS OF SODALITE-CANCRINITE PEGMATITES FROM THE VISHNEVOGORSK MIASKITE MASSIVE, SOUTH URALS [PDF]
Минералогия, 2016 A vein of cancrinite-sodalite pegmatite was mined in the western slope of Mount Kobelikha, in the bench bottom of the open pit of the Vishnevogorsk deposit, South Urals. Forty three minerals were found in the vein including several species, which require

Petrology, 2020 Mineral zoning in fenites around miaskite intrusions of the Vishnevye Mountains complex can be interpreted as a magmatic-replacement zonal metasomatic aureole (in D.S. Korzhinskii’s understanding): the metasomatic transformations of the fenitized gneisses under the effect of deep alkaline fluid eventually resulted in the derivation of nepheline syenite
