Graphitic shale
WebSchist has large, flattened grains of platy minerals like muscovite, biotite, and chlorite. These crystals are elongated and oriented roughly parallel to one another. Quartz and feldspar … WebWestern Australia has numerous recorded graphite prospects and occurrences. Almost all are found in graphitic schists or gneisses derived from the metamorphism of carbonaceous sedimentary rocks ranging from Archean to Mesoproterozoic age.

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. Shale is characterized by its tendency to split … See more Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding planes. … See more Shales are typically gray in color and are composed of clay minerals and quartz grains.

WebSchist is a medium-grained foliated metamorphic rock primarily made of platy minerals like biotite, muscovite, talc, and chlorite, with smaller amounts of bulky minerals like quartz and feldspar.
