Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Charnockite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Charnockite rock are vital in determining its Charnockite Texture and ...

Score: 5/5 (20 votes) . Answer : Option D) Both the models because each shows an electron in the outermost shell. Explanation : It is clearly seen that the model 1 and model 2 has the electronic configuration which is same for potassium. The reactivity in potassium is seen because of the one electron present in the outermost valence shell.

Oct 15, 2022The charnockite series originally was assumed to have developed by the fractional crystallization of a silicate magma (molten material). Subsequent studies have shown, however, that many, if not all, of the rocks are metamorphic, formed by recrystallization at high pressures and moderately high temperatures.

The charnockite series includes rocks of many different types, some being acid and rich in quartz and microcline, others basic and full of pyroxene and olivine, while there are also intermediate varieties corresponding mineralogically to norites, quartznorites and diorites. A special feature, recurring in many members of the group, is the ...

Charnockite is a felsic, melanocratic, holocrystalline, alkali granitic rock first described from the tombstone of Job Charnock in the graveyard of St. John''s garrison church, Calcutta, India (Holland, 1900).The rocktype is widespread in the Madras area (whence the gravestone originated—St. Thomas Mtn.) and is known from much of the highgrade terrane of Peninsular India.

In the valley of the South Branch of Naaman Creek, through Ardentown, is a group of charnockite boulders and finegrained mafic rock (probably amphibolitized gabbroid). The mafic rock is mostly nonmegacrystic with some coarsegrained and equigranular charnockite. On the ground around the boulders are small pieces that contain a clear example of a contact between coarsegrained and fine ...

charnockite (which is part of the Lofoten suite). After emplacement, the charnockite of Hopen underwent highpressure metamorphism, which converted fayalite+quartz to orthopyroxene (Ormaasen, 1977). Ormaasen (1977) thus recognizes two types of charnockites in the Hopen. Charnockite I retains primary Opx, whereas in Charnockite

Charnockite. (named for the founder of Calcutta, J. Charnock), a hypersthene granite typical of Precambrian assemblages that contain migmatites. Charnockite is composed of orthoclase, oligoclase, quartz, and hypersthene; it also often includes the garnets almandine and pyrope, as well as biotite, magnetite, and other minerals.

The charnockite is a massive quartzofeldspathic gneiss, with quartz and feldspar comprising more than 85 vol% of the rock. Plagioclase largely dominates over alkali feldspar and, thus, the rocks have tonalitic to granodioritic compositions ( they would be termed enderbite or charnoenderbite, rather than charnockite, on the classification of Streckeisen 1976).
