Metals in crude oils, asphaltenes, bitumen, and kerogen in molasse basin, southern Germany.
The content of Ni, V, and Co in malthenes and asphaltenes of southern German crude oils enabled the differentiation of 2 oil families in accordance with other geochem. parameters. Concerning Cr concns., all bitumen (1.2-11.1 ppm) fractions lie within the range of oil asphaltenes (0.9-22.7 ppm). The Se concns. are <0.2 ppm and <0.5 ppm in oil and oil asphaltenes, resp., but the oil is enriched in the bitumens (0.8-1.3 ppm).
