Ctype magmas: igneous charnockites and their extrusive

The Charnockite Magma Type is considered to be derived by melting of a hornblendefree or poor, LILEenriched fertile granulite source which had not been geochemically depleted by a previous partial melting event but which was dehydrated in an earlier metamorphism.

The Charnockite Geotherm Science

Charnockite, a hypersthenebearing granite, and other associated rocks of the charnockite series have a global distribution. These rocks, according to evidence from mineralchemical and experimental phase equilibrium relations, formed or recrystallized at temperatures between 800° and 900°C and at relatively shallow depths of 6 to 12 kilometers.

Zircon from charnockite gneiss, charnockite, and leucosome

Abstract The microgeochemistry of zircon was studied in three samples: charnockite gneiss (1594), charnockite (1594a), and migmatite leucosome Lc4 (1594c). Prismatic (Zrn I) and oval (Zrn II) zircon morphotypes are distinguished in the first two samples. Most zircon grains consist of twophase cores and overgrowth rims variable in thickness.
