Shale

Sedimentary Rocks

A fine-grained clastic sedimentary rock formed from mud, a mix of clay mineral flakes and silt-sized fragments of quartz and calcite, and the most common sedimentary rock on Earth. Its signature property is fissility, the tendency to split into layers less than a centimeter thick, and under low-grade regional metamorphism it becomes slate.

Pyrite, Materials

Pyrite forms in shale during early diagenesis of anoxic mud; cited via shale's own registered source since Pyrite carries only the generic mineral-wikipedia stub as its own source.

  • Lead section
    Shale is characterized by its tendency to split into thin layers (laminae) less than one centimeter in thickness. This property is called fissility. Shale is the most common sedimentary rock.
  • Lead section
    Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.
  • Associated With: Pyrite, Formation section
    Pyrite may be formed in anoxic mud at this stage of diagenesis.
