      The present paper records the occurrence of framboidal pyrite and algal pyrite in the Mussoorie phosphorite deposit. The significance of organic matter and sediment composition have also been discussed. The petrographic and analytical data indicate the dominant role of organic matter in the formation of pyrite. It is concluded from the textural study of pyrite that framboids have formed earlier in the sediment and subsequently the euhedral pyrite nucleated on them, gradually increasing in its abundance.
