Ganister and Blueschist


Blueschist and Ganister


Definition

Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.   
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

Formation

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.   
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

All about Ganister and Blueschist Properties

Know all about Ganister and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Blueschist is Foliated. Ganister appears Rough and Blueschist appears Dull and Banded. The luster of Ganister and Blueschist is dull. Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
