This paper synthesizes all known finds of Ethmodiscus ooze in the Eastern Indian Ocean and indicates areas of its occurrence. Accumulation of Ethmodiscus ooze is controlled by water circulation and relief of the ocean floor. Bedding of Ethmodiscus ooze has gradational layering and cyclicity caused by multiple redeposition of diatom tests. The maximum occurrence of Ethmodiscus rex in sediments corresponds to Late Pleistocene.
