New Data on Petrogeochemical Research of Pre-alpine Quartz Diorites and Granitoids of the Loki Crystalline Massif (lesser Caucasus)
Year: 2024
Type: article
Abstract: The issues of geochemistry and genesis of the Upper Devonian quartz diorites and Late Variscan granitoids of the pre-Alpine basement of the Loki crystalline massif are discussed. According to I, S and A types of the geochemical classification of granits, quartz diorites belong to S and partly M type granites, and granitoids belong to S and I types. The chemical composition of granitoids corresponds to normal, mostly normal alkaline-acid rocks. The granitoids and quartz diorites of the massif are characterized by the signs of magmatic rocks of volcanogenic-arc origin, which indicates mainly the subduction conditions of their formation.
