In this paper the author has put forward the results of his study of the manganese ore minerals of Jamda Valley under the reflecting microscope. He differs from Dr. Spencer (1948) who suggested that the ores are entirely composed of pyrolusite, and has identified five different manganese minerals under the microscope. These are: Psilomelane, Pyrolusite, Manganite, Polianite and Romanéchite.
