Shonkinite is an uncommon type of intrusive igneous rock found in Montana, Ontario, Canada, and the southeast Indonesian island Timor. The dominant materials that comprise the dark-colored rock are orthoclase feldspar and augite.
Shonkinite is closely related to several other relatively rare types of rock, such as theralite, essexite, and teschenite.
