Slate vs Limestone

Slate vs Limestone 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 Slate and Limestone Reserves. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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 Slate vs Limestone information and Slate vs Limestone characteristics in the upcoming sections.

Slate vs Limestone 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. Slate vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Slate and Properties of Limestone. Learn more about Slate vs Limestone in the next section. The interior uses of Slate include Bathrooms, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Slate and Limestone, they have various applications in construction industry. The uses of Slate in construction industry include As dimension stone and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.

More about Slate and Limestone

Here you can know more about Slate and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Slate and Limestone consists of mineral content and compound content. The mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt.

Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Slate is Dull and that of Limestone is Rough and Banded. Properties of rock is another aspect for Slate vs Limestone. Hardness of Slate and Limestone is 3-4. The types of Slate are Phyllite, Schist, and Slate whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Slate is light to dark brown while that of Limestone is white. The specific heat capacity of Slate is 0.76 kJ/Kg K and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Slate is heat resistant, impact resistant, pressure resistant, wear resistant whereas Limestone is pressure resistant.
