5 Formation

5.1 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.

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Siltstone vs Coal Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Siltstone and Coal Reserves. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Siltstone vs Coal information and Siltstone vs Coal characteristics in the upcoming sections.

More about Siltstone and Coal

Here you can know more about Siltstone and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Coal consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt and mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Siltstone vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Siltstone is Rough and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Siltstone vs Coal. The hardness of Siltstone is 6-7 and that of Coal is 1-1.5. The types of Siltstone are Not Available whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone is white while that of Coal is black.
