| Tartalmi kivonat: | There are significant differences among the results of the LOPATIN methods used for estimating the vitrinite reflectance. These differences made it justified to compare and to critically evaluate these methods. Four methods have been compared: two methods by LOPATIN published in 1971 and 1976, resp., and the methods of KARPOV an WAPLES. In addition to the differences caused by deviations of geosystems used for the correlation, the LOPATIN methods basically differ from each other in the character of the correlation relationship and in the reaction kinetic principles employed. The author thinks that the linear relationship between the logarithm of the vitrinite reflectance and that of the time-temperature index is better founded. For describing the geosystem published by Dow, the reaction kinetic principle is more adequate that are characterized by the following features: the activation energy does not depend on the temperature and, as a result of this, the change of the reaction rate by 10 °C decreases with the increase of. the temperature. This reaction kinetic principle is used by LOPATIN in his method published in 1976. |
