AB  - Biological markers in the alkane fraction of coal from the central and southern parts of the Kosovo basin (Yugoslavia) were analyzed by using computerized gas chromatography-mass spectrornetry (GC-MS). The presence of tricyclic diterpanes with pimarane and abictane structure and tctracyclic ditcrpanc 16α(H) phyllocladane indicated that coniferous resins participated in the formation of the organic mater of Kosovo basin coal. The presence of Dc-A lupanc proved the partipication of dicotyledonous gymnosperms in the formation of the organic matter, while the presence of pentacyclic triterpanes with hopane structure indicated that the degradation of the organic substance was caused by microorganisms of the bacterial type. The results of the GC-MS analysis of the biomarkcrs were used to estimate the degree of carbonification of the investigated coal. The presence of diterpanes with pimarane structure and the presence of monoaromatic hopane structure (D-ring), and the absence of 16β(H) phyllocladane and 18α(H)22,29,30 trisnorhopane (Ts), confirmed that Kosovo basin coal is of a low carbonification degree.

AB  - The naphthenic crude oil from the "W" oil-gas field differs from almost all other, paraffinic base oils discovered until now in the Yugoslav part of the Pannonian basin. In order to explain this difference, some geological and organic geochemical investigations were carried out. On the basis of the bulk and biomarker parameters, determined in oil samples taken from 13 producing wells located at different parts of the field, it is concluded that the crude oil throughout the field has an almost uniform composition. However, some differences in alkane content, due to biodegradation and/or water washing were found. In the northeast part of the field where a tilted oil-water layers shows an active hydrodynamism, and where the temperatures are the lowest and pressure gradients the highest, the isoprenoids pristane and phytane were detected in trace amounts-indicating the most intensive biodegradation. In the central part, where a hydrocarbon accumulation exists in a Miocene reservoir, somewhat lower biodegradation was observed. The crude oil from this field has probably a mixed terrestrial-marine origin and is derived from argillaceous source rocks sedimented in marine delta or brackish lakes. Specific maturation parameters confirmed that the "W" crude oil has reached a quite uniform and significant thermal maturation. Considering maturation parameters such as ratios C30 moretane/hopane and C29 αα(20S)/αα(20S)+(20R) steranes, as well as the presence of oleanane, it could be proposed that the "W" oil originates from a Pre-Tertiary source rock, at least an Upper Cretaceous one, unlike most Pannonian basin oils which are Tertiary in age. © 1990.
