Ganister and Latite

Ganister

Latite

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.

Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

Formation

Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Ganister and Latite Properties

Know all about Ganister and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Latite belongs to Igneous Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Latite is Aphanitic to Porphyritic. Ganister appears Rough and Latite appears Rough. The luster of Ganister is dull while that of Latite is subvitreous to dull. Ganister and Latite are 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 Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
