测定了德国阿尔卑斯山前陆南部9个不同中生代或第三纪储集岩层中17个油田的45个原油样品中元素S、V、Cr、Fe、Co、Ni、Zn、Se、Br、I、Ag和Hg的浓度。同时测定了15个油田水样中Na、Mg、S、Cl、Ca、Fe、Co、Cu、Zn、Br、Sr、I等元素的含量。分析技术以仪器中子活化分析为主，少量采用X射线荧光光谱法、原子吸收光谱法、发射光谱法和滴定法，硫、钒、镍、硒在不同油田的含量相对恒定，适用于区分不同类型的原油。根据硫、钒、镍的含量，可将这些原油分为以下三个显著的组群：1。(A)西部磨拉石盆地三叠系和下侏罗统原油。(B)西莫拉斯的Bausteinschichten（下查提安）原油（除了艾廷根的原油）。在东部Molasse原油从Priabonian砂，马尔姆和下奥陶洛斯。3. (C)东部磨拉石盆地“Ampfinger Schichten”的次生蚀变原油。艾廷根原油的S和V含量异常高，分别提高了3倍和20倍。原油中的微量元素分布与油田伴生沃茨中的微量元素分布之间没有联系。只有原油中的I含量与相应油田沃茨中的I含量显著相关。
The concentrations of the elements S, V, Cr, Fe, Co, Ni, Zn, Se, Br, I, Ag and Hg were determined in 45 crude oil samples of 17 oilfields originating from nine different Mesozoic or Tertiary reservoir rock formations in the southern German Alpine Foreland. Furthermore, the elements Na, Mg, S, Cl, Ca, Fe, Co, Cu, Zn, Br, Sr and I were determined in 15 oilfield water samples. The analytical technique was mainly instrumental neutron-activation analysis; to a minor degree X-ray fluorescence spectrometry, atomic absorption and emission spectrometry as well as titrimetric methods were applied.The amounts of S, V, Ni and Se are relatively constant in the different oilfields; therefore they are suitable for distinguishing between different classes of oil. The crudes can be divided into the following three significant groups by their concentrations of S, V and Ni:1.(A) Triassic and Lower Jurassic crudes of the Western Molasse Basin.2.>(B) Crudes from the Bausteinschichten (Lower Chattian) in the Western Molasse (except the one from Aitingen). In the Eastern Molasse crudes from Priabonian sands, Malm and Lower Cretaceous.3.(C) Secondary altered crudes of the “Ampfinger Schichten” in the Eastern Molasse Basin.The crudes of Aitingen are exceptional with their high content of S and V, being enhanced three and twenty times, respectively.Relations between trace-element distributions in crudes and in accompanying oilfield waters could not be found. Only the amounts of I in crudes are significantly correlated with those from the corresponding oil field waters.
