Adamellite and Ganister


Ganister and Adamellite


Definition

Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz   
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.

Formation

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.   
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Adamellite and Ganister Properties

Know all about Adamellite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Adamellite belongs to Igneous Rocks while Ganister belongs to Sedimentary Rocks.Texture of Adamellite is Porphyritic whereas that of Ganister is Clastic, Granular, Rough. Adamellite appears Veined or Pebbled and Ganister appears Rough. The luster of Adamellite is dull to grainy with sporadic parts pearly and vitreous while that of Ganister is dull. Adamellite is available in black, grey, orange, pink, white colors whereas Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Adamellite are curling, gemstone, laboratory bench tops, tombstones and that of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones.
