Igneous charnockite

Web1 dec. 2010 · The anorthosite-mangerite-charnockite-granite (AMCG) suite of rocks in North America is typically regarded as an association of two rock suites that are coeval but not comagmatic ( Emslie et al., 1994; McLelland et al., 1994; Bickford et al., in press ). Weband Frost (2008) reviewing the varied and controversial aspects of the term charnockite, suggested that the term charnockite should be a general term that is applied to orthopyroxene-bearing granitic rock that is clearly of igneous origin or that is present as an orthopyroxene-bearing granitic orthogneiss within a granulite terrane.

Web1 aug. 2024 · The meionite content of scapolite indicates that the peak metamorphic temperature reached a minimum of 790 °C. In the outermost rim of the calc-silicate scapolite is partially replaced by clinopyroxene, probably as a result of the influx of Mg bearing fluids from the surrounding charnockite gneiss during uplift and decompression.
