Ein geochemisches Profil durch den Lias alpha (zur Frage der Entstehung des Erdöls)
Review articleOpen access

AbstractA systematic study of trace elements and isotopes in lithological profiles and connected oils might lead to the determination of source rocks. This paper is a first attempt in this line; results will be conclusive only after a study of the whole stratigraphical sequence has been completed.There is practically no difference between the ratio 12C: 18C in bituminous shales and oils from the Lias alpha. It seems that during bituminization and oil-forming the ratio is changed as little as in the forming of coals. No connexion was found between degree of salinity of sedimentational environment, and 12C: 13C ratio of oils present in such sediments. Of trace metals, oils contain notably less Cr than the shales of their vicinity; the same relationship is observed between tars (“oils”) and their parent oil shales.
