Siltstone and Suevite
Definition
Definition
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Siltstone and Suevite Properties
Know all about Siltstone and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Siltstone belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Siltstone is Clastic whereas that of Suevite is Earthy. Siltstone appears Rough and Suevite appears Banded. The luster of Siltstone is dull while that of Suevite is earthy. Siltstone is available in brown, red, reddish brown colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Siltstone are raw material for the manufacture of mortar, soil conditioner and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
