    Study Notes

    Inorganic Land-Derived Sedimentary Rocks

    • Conglomerate: consists of pebbles, cobbles, and/or boulders embedded in sand, silt, and/or clay, with rounded fragments
    • Breccia: consists of angular fragments
    • Sandstone: composed of quartz, feldspar, and clay minerals, with grain size ranging from 0.006 to 0.2 cm
    • Siltstone: composed of fine-grained particles, with grain size ranging from 0.0004 to 0.006 cm
    • Shale: composed of compact, fine-grained particles, with grain size less than 0.0004 cm, and may split easily

    Chemically and/or Organically Formed Sedimentary Rocks

    • Rock salt (Halite): formed from chemical precipitates and evaporites, with fine to coarse crystalline texture
    • Gypsum: formed from chemical precipitates and evaporites, with crystalline texture
    • Dolostone: formed from bioclastic or crystalline calcite, with microscopic to very coarse texture
    • Limestone: formed from precipitates of biologic origin or cemented shell fragments, with microscopic to very coarse texture
    • Bituminous coal: formed from compacted carbon plant remains
