1 Definition

1.1 Definition

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

5.1 Formation

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.

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Coal vs Conglomerate 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 Coal and Conglomerate Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. 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 Coal vs Conglomerate information and Coal vs Conglomerate characteristics in the upcoming sections.

Coal vs Conglomerate Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Coal vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Conglomerate. Learn more about Coal vs Conglomerate in the next section. The interior uses of Coal include Not available whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Coal and Conglomerate, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.

More about Coal and Conglomerate

Here you can know more about Coal and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Conglomerate consists of mineral content and compound content. The 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 and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Coal is Veined or Pebbled and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Coal vs Conglomerate. The hardness of Coal is 1-1.5 and that of Conglomerate is 2-3. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Conglomerate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Conglomerate is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Conglomerate is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Conglomerate is heat resistant.
