A new occurrence of a calco-alkaline granite intrusion from the Frederikshaab District, South Greenland

Abstract

A newly discovered, fluorite-bearing, calco-alkaline granite intrusive from the Frederikshaab District, Southwest Greenland, is described. The granite is closely related to some rapakivi granites, pyterlite and wiborgitc, from the Viipuri area, Finland, as described by Wahl (1925). The relation between this intrusive and other "younger intrusives" is discussed, with respect to the fluorine content of the group of younger intrusives (Wegmann, 1938).
