    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. It is the most common sedimentary rock. The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than i

    There the oil shale is crushed and loaded into a reactor known as a retort, where the temperature is increased to about 400–500°C to decompose the kerogen and release the shale oil. In in situ-retorting heat is applied directly to the rocks underground and the shale oil obtained is extracted in a manner similar to petroleum extraction.

  • Shale: Sedimentary Rock Pictures, Definition & More

    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." Shale is distinguished from other mudstones because it is fissile and laminated.
