This is a comperative study of the oxic-anoxic transition in               modern sediments of the Black Sea and of some Pennsylvania shales               in the U.S.  The Black Sea core samples and the Pennsylvania rock               samples from oxic, transitional, and anoxic environments have                   been collected.  The PI will undertake sulfur isotopic analysis                 of pyrite and chemical analyses for pyrite sulfur, organic                      carbon, reactive and total iron, and inorganic and organic                      phosphorus.  The chemical analyses will be closely integrated                   with determinations of sedimentary texture (bioturbated,                        laminated, etc.) via X-ray slab techniques.  The result will be                 used to test current theories and develop new paradigme for: (1)                the discriminaation of normal marine from euxinic sediments; (2)                the discrimination of syngenetic from diagenetic pyrite; (3) the                formation of phosphorus (and manganese) enrichments within                      oxic/anoxic transition zones.
