dc.description.abstractHigh resolution mass spectrometry indicates that the isotopic abundance of (50)vanadium (V) of the Late Cretaceous La Luna petroleum asphaltenes and related source kerogen of marine origin (both highly enriched with V GT 2000 ppm) is higher by about 3.5 % than that of an inorganic vanadium source (VOSO4. 5H(2)O, Merck). It is proposed that the difference in the V-50/V-51 values between theta Luna source kerogen/the associated petroleum asphaltenes and the inorganic soul ce can be best ascribed to the biological processing of seawater V. The fact that the isotopic compositions of V vary over a very narrow range (2.46-2.50) suggest an essentially same (or similar) and fixed biological source of V.en
