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
