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.

Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

Etymology

From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

From German Schalstein laminated limestone, and Schalgebirge layer of stone in stratified rock. From Old English scealu in its base sense of- thing that divides or separate,

Formation

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

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

All about Ganister and Shale Properties

Know all about Ganister and Shale properties here. All properties of rocks are important as they define the type of rock and its application. Ganister and Shale belong to Sedimentary Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Shale is Clastic, Splintery. Ganister appears Rough and Shale appears Muddy. The luster of Ganister and Shale is dull. Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Shale is available in black, brown, buff, green, grey, red, 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 Shale are creating artwork, pottery.
