Tachylite and Sandstone


Sandstone and Tachylite


Definition

Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt   
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

Formation

Formation
Tachylite 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.   
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Tachylite and Sandstone Properties

Know all about Tachylite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Tachylite belongs to Igneous Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Tachylite is Vitreous whereas that of Sandstone is Clastic, Granular, Rough. Tachylite appears Glassy and Sandstone appears Rough. The luster of Tachylite is resinous while that of Sandstone is dull. Tachylite is available in black, dark brown colors whereas Sandstone 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 Tachylite are cemetery markers, creating artwork and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
