and E. H. Kraus, Zeits. K~:qst. Min. 1900, XXXIII, 36. Fedorovite,

1898, p. 707 (Glaukamphibole). A group-name to include the alkaliamphiboles,
glaucophane, gastaldite, and crossite, which are of dynamometamorphic
origin, as distinct from the arfvedsonite-amphiboles, arfvedsonite,
riebeckite and hastingsite, which occur only as original constituents
in igneous rocks.
