Summary

The paper gives an account of the mineragraphic study of the managanese ore-minerals collected from Satak, Beldongri, Lohdongri and Kachurwahi managanese mines in Nagpur District, Bombay State. The ore-minerals identified in polished sections are Braunite, Sitaparite, Hollandite, Jacobsite, Hausmannite, Manganite, Pyrolusite and Psilomelane. In addition, two unidentified minerals have been fully described and the problem of their nomenclature is discussed. Unusual textural features such as the reaction rim of Braunite between Jacobsite and Pyrolusite and Jacobsite and gangue have been described along with a detailed description of the more common textural features. The mineral paragenesis, based on textural features and physicochemical considerations, has been determined. It is followed by a short discussion on the relationship of the ore-mineral assemblages and the type of metamorphism they have suffered.
