Granulites are a type of high-grade metamorphic rock that forms under conditions of high temperature and pressure. They are characterized by the presence of granular minerals, which means that the mineral grains are roughly equidimensional and roughly the same size. The most common minerals found in granulites include feldspar, pyroxene, amphibole, and garnet.Granite (/ ˈ ɡ r æ n ɪ t /) is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions.These range in size from dikes only a few centimeters ...Granite - Wikipedia2.6.1 Introduction Trivandrum granulite block (TGB), also designated as the Kerala Khondalite Belt (KKB), is the southernmost crustal block in the SGT and occurs to the south of AKSZ (see Fig. 2.41 ).

Fluid-present granulites can be formed by relatively low-T dehydration reactions, in the presence of a fluid dominated by a species other than H 2 O (e.g., CO 2).Small quantities of H 2 O-rich fluid may be present at the onset of granulite facies conditions (≥ 650°C).

Granulite (Latin granulum, "a little grain") is a name used by petrographers to designate two distinct classes of rocks. According to the terminology of the French school it signifies a granite in which both kinds of mica (muscovite and biotite) occur, and corresponds to the German Granit, or to the English muscovite biotite granite.The term granulite originated in the Granulitgebirge of Saxony, where three types can be recognized ( Watznauer, 1969 ): (1) pyroxene-free quartz-feldspar granulite, (2) pyroxene-bearing quartz-feldspar granulite, and (3) plagioclase-pyroxene granulite.
