  • Some general information on oil shale

    Oil shale is a fine grained sedimentary rock formed from the compaction and heating of organic rich sediments and containing significant amounts of kerogen. Its name is, in fact, a bit misleading, as the rock itself is not necessarily shale, and the organic matter it contains is not oil.

  • How is a shale rock formed? | AnswersDrive

    Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call 'mud.' This composition places shale in a category of sedimentary rocks known as 'mudstones.' 'Laminated' means that the rock is made up of many thin layers.

  • Shale - Wikipedia

    Shale is a fine-grained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility.

  • What Environment Is Likely to Form Siltstone or Shale .

    Siltstone and shale, two types of sedimentary rock called clastic rock, form from "clasts" -- that is, fragments of other rocks or minerals. When the rock fragments are buried and compacted, they form sedimentary layers. In the case of siltstone and shale, the clasts are tiny silt and clay particles.

  • Hermit Formation, Grand Canyon

    The Hermit Formation redbeds provide much of the red color that paints Grand Canyon. The red color is from iron oxide—these rocks are rusty!
