Sedimentary rocks

Sedimentary rocks

  • Diatomaceous earth
    Diatomaceous earth (pronunciation: /ˌdaɪ.ətəˌmeɪʃəs ˈɜːrθ/), also known as D.
  • Gypsum
    Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O.
  • Loess
    Loess (pronunciation: /ˈloʊ.əs/, /ˈlʌs/, /ˈlɛs/, or UK /ˈlɜːrs/; from German Löss [lœs]) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust.
  • Sedimentary rock
    Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water.
  • Bauxite
    Bauxite, an aluminium ore, is the world's main source of aluminium.
  • Facies
    In geology, a facies (pronounced variously as /ˈfeɪʃiːz/, /ˈfeɪsiːz/ or /ˈfæʃiːz/ ['faysheez', 'fayseez' or 'fash-eez']; plural also 'facies') is a body of rock with specified characteristics, which can be any observable attribute of rocks such as their overall appearance, composition, or condition of formation, and the changes that may occur in those attributes over a geographic area.
  • Sintering
    Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.
  • Marl
    Marl or marlstone is a calcium carbonate or lime-rich mud or mudstone which contains variable amounts of clays and silt.
  • Torbanite
    Torbanite, also known as boghead coal, is a variety of fine-grained black oil shale.
  • Grain size
    Particle size, also called grain size, refers to the diameter of individual grains of sediment, or the lithified particles in clastic rocks.
  • Bituminous coal
    Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen.
