Shale and Granulite


Granulite and Shale


Definition

Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles   
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Etymology
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,   
From Latin granulum, a little grain or fine grained

Formation

Formation
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.   
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Shale and Granulite Properties

Know all about Shale and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Shale belongs to Sedimentary Rocks while Granulite belongs to Metamorphic Rocks.Texture of Shale is Clastic, Splintery whereas that of Granulite is Granoblastic. Shale appears Muddy and Granulite appears Veined or Pebbled. The luster of Shale is dull while that of Granulite is vitreous. Shale and Granulite are available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Shale are creating artwork, pottery and that of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
