Kyanite-Gedrite Parageneses
Discussion of the genesis of kyanite-amphibole associations in amphibolites has so far been limited to assemblages involving common hornblende (1). Striking examples of an association of kyanite with rhombic amphibole (gedrite) now known from the Archaean gneisses of the White Sea area, Russia, visi...

| Summary: | Discussion of the genesis of kyanite-amphibole associations in amphibolites has so far been limited to assemblages involving common hornblende (1). Striking examples of an association of kyanite with rhombic amphibole (gedrite) now known from the Archaean gneisses of the White Sea area, Russia, visited by the Northern Excursion of the International Congress in 1937, probably provide one of the first records of this paragenesis in the literature. 1 The rocks of the region include coarse-grained garnet and kyanite rich gneisses associated with amphibolites in the Shueretsky district of Karelia, and have been described by Ignatiev (2). |
