    travertine
  26. composed of small spheres called ooids forming in shallow bodies of water
    oolitic limestone
  27. composed of microscopic shells of diatoms
    diatomite
  28. formed in places such as salt flats in bolsons
    evaporite deposits
  29. formed from the accumulation of plant matter in an oxygeon poor aquatic environment such as a swamp or bog
    coal
  30. plant matter that may turn into coal
    peat
  31. formed by shallow burial under sediment
    lignite
  32. formed by deeper burial
    bituminous coal
  33. anthracite
    formed by very deep burial
  34. carbonaceous rock
    any rock in which organic matter becomes trapped before the sediments formed a rock
  35. formed by some type of organic matter buried under sediment
    oil and natural gas
  36. reservoir rock
    rock in which oil and gas is found
  37. cap rock
    impermeable rock which prevents the upward movement of oil and gas
  38. diagenesis
    all the chemical, physical and biological changes which take place after a sediment is deposited in order to form a rock
  39. lithification
    process by which loose sediment turns into a solid rock
  40. compaction
    usually caused by burial under other sediments
  41. cementation
    sediment particles being glued together
  42. strata
    one layer of rock
  43. bedding plane
    the junction between beds

    beds at various, odd angles
  45. ripple marks
    waves on the surface of sediment
  46. current ripple marks
    formed by flowing water
  47. oscillation ripple marks
    formed by sloshing water
