Description Pyritized ooids in association with turbidites were observed in a box core collected at a depth of 3627 m from the Arabian Sea Basin. Ooids having a shallow water origin were transported to the present depth by turbidity currents or slumping. Occurrence of pyrite at turbidite intervals suggests that pyritization in high organic carbon and H2S abundant environments was mainly controlled by the supply of reactive iron. From the distribution of pyrite in the core it is inferred that reactive iron necessary for pyritization was transported as colloidal oxyhydroxides from the shelf region along with the ooids
