Burkeite is a rare mineral that was discovered in the late 19th century and named after the American geologist and mineralogist Thomas Burke. It is a sulfur and magnesium inosilicate mineral with the chemical formula Mg2Si2O5(OH)4. The mineral occurs as small grains in alpine-type fissures and veins in hydrothermally altered rocks, primarily in Manitoba and Quebec in Canada.

Burkeite has a vitreous luster and is colorless to white in appearance. It generally forms ashedral crystals, though it can also be massive or incrustations. It has a Mohs hardness of 4-4.5 and a specific gravity of 2.64-2.69. Burkeite has two directions of perfect cleavage and fractures easily.

Burkeite is an important source of rare metals such as zinc, manganese, copper and nickel, which are mined from it. It is also used in the manufacture of certain specialty glass products, such as optical lenses and ceramics. It is also used for fertilizer in agriculture. In addition, it is an important mineral for geologists as its presence indicates certain geological processes, such as hydrothermal alteration of rocks.
