An unstable manganese oxide that dehydrates to birnessite.
Crystallochemical data on synthetic material.
The original material was reported from Yuno-Taki waterfall, Me-akan volcano, Akan National Park, Kushiro Province, Hokkaido Island, Japan.
A new proposal for 'buserite' would most probably be successful (E. Burke, Mindat forum, 2005). The statement by Burns et al. [Am. Mineral. 68, 972-980 (1983)], "buserite was accepted as a mineral name by the commission on New Minerals by a small majority (M. Fleischer, personal communication, 1974).", is not correct (E. Burke, Mindat forum, 2005).
