Paper Abstract

Study of the inner structure, mineral, chemical and isotope composition of siderite and phosphate-siderite concretions from the upper Jurassic deposits of the Viatka-Kama basin has been made. A possible mechanism of their formation is discussed. A number of mineralogical and isotopic features indicate that the siderites and phosphates were formed at the diagenetic stage by the agency of both inorganic and microbial processes.
