| contents | Todorokite is a very abundant manganese oxide mineral in many deposits in Cuba and has been noted from other localities. Six new analyses are givenl they lead to the approximate formula (Na, Ca, K, Mn+2)(Mn+4, Mn+2, Mg)6O12.3H2O. Electron diffraction data show the mineral to be orthorhombic, or monoclinic with beta near 90°. The x-ray powder pattern is indexed on a cell with a=0.75A, b=2.849A, c=9.59A, beta=90°. A differential thermal analysis curve is given. |
