Not to be confused with Torbernite or Tobermorite.

Torbanite, also known as boghead coal, is a variety of fine-grained black oil shale. It usually occurs as lenticular masses, often associated with deposits of Permian coals.[1][2] Torbanite is classified as lacustrine type oil shale.[3]

Torbanite is named after Torbane Hill near Bathgate in Scotland, its main location of occurrence.[4] Other major deposits of torbanite are found in Pennsylvania and Illinois, USA, in the Transvaal of South Africa, in the Sydney Basin, New South Wales, Australia,[5] the largest deposit of which is located at Glen Davis, and in Nova Scotia, Canada.[1][4]

Organic matter (telalginite) in torbanite is derived from lipid-rich microscopic plant remains similar in appearance to the fresh-water colonial green alga Botryococcus braunii.[1][2][4] This evidence and extracellular hydrocarbons produced by the alga have led scientists to examine the alga as a source of Permian torbanites[6] and a possible producer of biofuels.[7] Torbanite consists of subordinate amounts of vitrinite and inertinite; however, their occurrence vary depending of deposits.[4]

Torbanite typically comprises 88% carbon and 11% hydrogen.[1] Paraffin oil can be distilled from some forms of torbanite, a process discovered and patented by James Young in 1851.
