“…Their geochemical signature indicates a within-plate tholeiitic source [8,17]. In the northern part of Wedel Jarlsberg Land (Chamberlindalen area), a suite of well-preserved alkali cumulates is present [18]. These rocks are considered to have formed during the same event as the prevalent within-plate tholeiites in this area.…”

A recent increase in fieldwork activity within the Southwestern Basement Province (SBP) of Svalbard followed by detailed geochronological and petrological studies has allowed recognition of previously unknown magmatic and metamorphic events in the studied region. These discoveries of, e.g. true c. 950 Ma granitic magmatism, c. 640 Ma Torellian metamorphism, completely new localities of high-pressure rocks and a c. 360 Ma Ellesmerian, Barrovian-type metamorphic sequence emphasize the importance of further research in this part of the Svalbard Archipelago. Paleogene tectonic overprint of the SBP, manifested by the West Spitsbergen Fold and Thrust Belt, is an additional challenge for geologists working in this part of Svalbard's crystalline basement, and must be taken into account in all interpretations of pre-Cenozoic structures. Several enigmatic issues concerning the evolution of the SBP remain unanswered. Hence, there is a need for continued research in this key area for understanding the geological evolution of the northern Barents Shelf and High Arctic in general.

“…Для інтрузивних порід абісальної фації характерні амфіболи гастингситового та лужного складу з нижчим вмістом титану, як це зазначено в одній з авторських публікацій (Kryvdik, 2017). Хоча деякі дослідники (Gołuchowska et al, 2016) вважають, що керсутити можуть кристалізуватись на глибині 30-50 км.…”

Ferry-kaersutite as a rare mineral have been found in North-Western part of the Ukrainian Shield where alkaline-ultrabasic rocks of jacupirangite-melteigite series are widespread. Ferry-kaersutite occurs in essexite that form thin veins and apophyses from dikes of porphyry-like alkaline-ultrabasic rocks. By results of microprobe analyses ferry-kaersutites are of such composition (%): 39—40 SiO2; 4.6—5.07 TiO2; 14.6—14.9 Al2O3; 16.9—18.4 FeOtot; 7.95—8.09 MgO; 10.5—11.0 CaO; 2.4—2.9 Na2O; 2.7—2.9 K2O. In alkaline-ultrabasic rocks of this region different more magnesian amphiboles (pargasites, richterites, magnesio-riebeckite, katophorite and other intermediate varieties) are present. Some of these amphiboles are enriched in TiO2 (to 2.9—3.2%). It is assumed that studied ferry-kaersutite has formed at quick crystallization and partly contamination of alkaline-ultrabasic melts in veins and apophyses among country granitoids.
