Metamorphism of Sedimentary Manganese Deposits
Acta Mineralogica-Petrographica, Szeged, XX/2, 325—336, 1972. METAMORPHISM OF SEDIMENTARY MANGANESE DEPOSITS SUPRIYA ROY ABSTRACT: Metamorphosed sedimentary deposits of manganese occur extensively in India, Brazil, U. S. A., Australia, New Zealand, U. S. S. R., West and South West Africa, Madagascar and Japan. Different mineral-assemblages have been recorded from these deposits which may be classi- fied into oxide, carbonate, silicate and silicate-carbonate formations. The oxide formations are represented by lower oxides (braunite, bixbyite, hollandite, hausmannite, jacobsite, vredenburgite •etc.), the carbonate formations by rhodochrosite, kutnahorite, manganoan calcite etc., the silicate formations by spessartite, rhodonite, manganiferous amphiboles and pyroxenes, manganophyllite, piedmontite etc. and the silicate-carbonate formations by rhodochrosite, rhodonite, tephroite, spessartite etc. Pétrographie and phase-equilibia data indicate that the original bulk composition in the sediments, the reactions during metamorphism (contact and regional and the variations and effect of 02, C02, etc. with rise of temperature, control the mineralogy of the metamorphosed manga- nese formations. The general trend of formation and transformation of mineral phases in oxide, carbonate, silicate and silicate-carbonate formations during regional and contact metamorphism has, thus, been established. Sedimentary manganese formations, later modified by regional or contact metamorphism, have been reported from different parts of the world. The most important among such deposits occur in India, Brazil, U.S.A., U.S.S.R., Ghana, South and South West Africa, Madagascar, Australia, New Zealand, Great Britain, Japan etc. An attempt will be made to summarize the pertinent data on these metamorphosed sedimentary formations so as to establish the role of original bulk composition of the sediments, transformation and reaction of phases at ele- vated temperature and varying oxygen and carbon dioxide fugacities in determin- ing the mineral assemblages in these deposits. -

The general usage of the term is to include as pseudomorphs both petrifactions and molds, and also: (1) Any mineral change in which the outlines of the original mineral are preserved, whether this surface be a euhedral crystal form or the irregular bounding surface of an embedded grain or of an aggregate. (2) Any mineral change which has been accomplished without change of volume, as evidenced by the undistorted preservation of an original texture or structure, whether this be the equal volume replacement of a single crystal or of a rock mass on a geologic scale. -
