| contents | According to geochemical analyses carbonaceous sediments from deep basins of the Baltic Sea containing 3-5% of organic carbon are enriched in some metals such as Cu, Mo, Ni, Pb, Zn, V, and U relative to shallow-water facies of the Bay of Finland. These metals also enrich (relative to background values in clayey rocks) ancient carbonaceous shales, where the average Cu and V contents are slightly higher and that of Mo, Pb, and Zn lower than in deep-sea carbonaceous sediments of the Baltic Sea. In addition, the deep-sea carbonaceous sediments of the Baltic Sea are enriched (but less notably than ancient shales) in Ag, As, Bi, and Cd. These data confirm previous assumptions that carbonaceous sediments accumulating now in seas and oceans can be considered as recent analogs of ancient metalliferous shales. |
