1.1 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.

Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine

5 Formation

5.1 Formation

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

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

All about Ganister and Pyroxenite Properties

Know all about Ganister and Pyroxenite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Pyroxenite belongs to Igneous Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic. Ganister appears Rough and Pyroxenite appears Layered, Banded, Veined and Shiny. The luster of Ganister is dull while that of Pyroxenite is dull to vitreous to submetallic.
