The bedded manganese oxide deposits of Iwasaki distrct, Aomori Prefecture occur in most cases in tuffaceous sandstone of the upper Miocene age. The mother rock of these deposits is slightly affected by the hydrothermal alteration, and the ore is characterized by the mineral composition of a single manganese mineral, todorokite. The mineral is identified mainly by the X-ray powder method and chemical and differential thermal analyses. The chemical formula is (Mn^<2+>_<0.58> Ca_<0.09> Mg_<0.20> Ba_<0.04>)_<0.90> Mn^<4+>_<3.06> O_<7.00>・2.1 H_2O which agrees well with Mn^<2+>Mn_3^<4+>O_7・2-xH_2O given by L.T.Larsen in 1962.
