Abstract

Different morphological forms of pyrite such as idiom orphic, concretionary and intraclastic varieties from the sedimentary ores of Amjhore, India are described. The concretionary pyrite is classified into: (1) loosely packed concretion, (2) compact concretion, (3) concentric concretion, (4) crescent shaped concretion, and (5) shard-shaped and irregular concretions. The significance of different morphologies exhibited by the pyrite and their textural relationships are briefly discussed.
