Charnockite microstructures: From magmatic to metamorphic

For the purpose of this paper, we would like to comment on the charnockite definition introduced by Frost and Frost (2008). Frost and Frost (2008) define charnockites as (p. 41): “…an orthopyroxene (or fayalite)-bearing granitic rock that is clearly of igneous origin or that is present as an orthogneiss within a granulite terrane.” Our first remark on this definition is that we would ...All the charnockites (hypersthene-bearing granites) have been traditionally described as basic, intermediate, and acid variety based on the composition and textural characteristics with gradual and continuous variations.Charnockite - an overview | ScienceDirect Topics2.

Charnockite - Metamorphic Rocks - Sandatlas

Charnockite is a granofels that contains orthopyroxene, quartz, and feldspar. Charnockite is frequently described as an orthopyroxene granite. Granites are felsic rocks that usually contain no or very little pyroxene.The Neoproterozoic charnockite–granite association of Okpella intrudes metasedimentary and migmatite-gneiss complex rocks in the eastern Igarra Schist Belt, southwestern Nigeria. In order to unravel the complex processes involved in the formation and tectonic evolution of the Igarra Schist Belt during the Neoproterozoic, detailed field, petrographic and whole-rock geochemical study of the ...Petrography and geochemistry of Neoproterozoic charnockite–granite ...كاسريات الحجر (الاسم العلمي: Saxifragales) هي رتبة من النباتات تتبع طبقة من طائفة ثنائيات الفلقة.
