Kaňkite
Kankite is a mineral with the chemical formula Fe3+AsO4·3.5(H2O). Kankite is named for the locality that yielded first specimens Kaňk, Czech Republic.〔 Kankite forms in old (1200- to 1400-year-old) mine dumps.〔 It is yellowish-green on fresh exposure, with a paler greenish yellow on exposure to air.
==Properties==
Kankite is a monoclinic mineral, meaning it is a mineral system having 3 unequal axes of which one is at right angles with the other two. It has an uneven fracture and has a hardness of 2–3 (gypsum–calcite). It is translucent yellowish-green in color with a grayish yellow streak. Its luster is dull to vitreous. Kankite contains the elements arsenic, iron, hydrogen and oxygen.〔(), Frost, Ray L. and Cejka, Jin and Keeffe, Eloise C. and Sejkora, Jiri (2009)''Raman Spectroscopic study of the mixed anion sulphate-arsenate mineral pamnauite''Journal of Raman Spectroscopy, 40(11) pp. 1547–1550.〕 It was approved by the IMA in 1976. Its habit is botryoidal, "grape-like" rounded forms (e.g. malachite). It forms encrustations, crust-like aggregates on matrix. The specific gravity of Kankite is 2.70.〔
