|Geological scheme of Gremyakha-Vyrmes massif. Alkaline granites located on the North (elongated crosses). (Kukharenko et al., 1971)|
|Materials of prospecting work in 1970's.|
|Aegirinite. Alkaline metasomatic rock.|
|Old prospecting ditch.|
|Fig. 1. All three Al2[SiO4]O modifications that has been formed due to different processes occured here. Kyanite as a paramorphose after andalusite, sillimanite as a product of thermal reaction, andalusite as relict in newly formed muscovite aggregate. XPL.|
|Fig. 2. The same field, PPL.|
|Fig. 3. Staurolitization. Staurolite replaces kyanite crystal. PPL.|
Fig. 4. Fibrous sillimanite aggregate, muscovitization and chloritization of biotite. PPL.
Figure 1 The relationships of minerals in the altered ultramafic rocks (a) and carbonate (b). a) The aegirinite alteration in contact with carbonatites: replacement of ilmenite (Ilm) by titanite (Ti), aegirine (Aeg) by alkaline amphibole (Amf). Transmitted polarized light, - 40x. b) Calcite (Calc) carbonatite with relict of albite (Ab) and deformed crystal mica (Mc). Transmitted light, crossed nicols, 40x.
