PORPHYRINS IN THE EVALUATION OF GENETIC RELATIONSHIP OF CRUDE OILS IN THE PERIBALTIC SYNECLISE AREA

Summary

The paper presents the main theoretical assumptions in geochemistry of porphyrins, and the possibilitie of interpretation, which ensue from the studies on the occurrence of compounds in crude oils and rock bitumens, for the solution of problems related to genesis and migration of crude oil. Based on the interpretation of crude oil porphyrins the author has made an evaluation of the genetic relationship of the crude oil manifestations observed within the Peribaltic Syneclize area, suggesting the position of mother rocks of these crude oils and trying in this way to determine the age of the separated types of crude oils. The conclusions of genetic nature, based on the analysis of the differentiation in character and concentration of the porphyrin compounds found in the crude oils examined, have been drawn in a confrontation with the general chemical nature of these crude oils, with regarded to the geological conditions of their occurrence.
