Siltstone and Marble
Definition
Definition
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation
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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Siltstone and Marble Properties
Know all about Siltstone and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Siltstone belongs to Sedimentary Rocks while Marble belongs to Metamorphic Rocks.Texture of Siltstone is Clastic whereas that of Marble is Granular. Siltstone appears Rough and Marble appears Veined and Shiny. The luster of Siltstone is dull while that of Marble is dull to pearly to subvitreous. Siltstone is available in brown, red, reddish brown colors whereas Marble is available in black, blue, brown, grey, pink, white colors. The commercial uses of Siltstone are raw material for the manufacture of mortar, soil conditioner and that of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
