shale

     

Shale (also calle mudstone) is a fine-grained sedimentary rock whose original constituents were clay minerals or muds. It is characterized by thin laminae breaking with an irregular curving fracture, often splintery and usually parallel to the often-indistinguishable bedding plane. This property is called fissility. Non-fissile rocks of similar composition but made of particles smaller than 1/16 mm are described as mudstones. Rocks with similar particle sizes but with less clay and therefore grittier are siltstones. Shale is the most common sedimentary rock.

Trivia about shale

  • More than half of sedimentary rock is this type from which oil & natural gas can be obtained
  • Slate is commonly formed by the metamorphism of this rock
  • Clay & mica minerals in this sedimentary rock cause it to split into thin layers
  • Crude oil can be extracted from this rock, the most abundant sedimentary rock in the Earth's crust
  • A bed of this oil- & fossil-bearing rock from the Cambrian period was famously discovered near Mt. Burgess in 1909
