The stromatolitic phosphorites are found for the first time in the Lesser Himalayan carbonate formations of Far Western Nepal. The phosphorites are confined to the cherty dolomite member which is a part of a thick succession of slate, limestone and dolomite. This paper deals with the petrography of the stromatolitic phosphorite and their chemical composition. The shallow marine environment of phosphate deposition is indicated.
