5 Formation

5.1 Formation

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

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

All about Sandstone and Amphibolite Properties

Know all about Sandstone and Amphibolite properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Amphibolite belongs to Metamorphic Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Amphibolite is Banded, Foliated, Massive. Sandstone appears Rough and Amphibolite appears Foliated. The luster of Sandstone is dull while that of Amphibolite is vitreous to dull. Sandstone and Amphibolite 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 Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums and that of Amphibolite are cemetery markers, commemorative tablets, creating artwork.
