Abstract

The paper considers the criteria of influence of trappean magmatism on the petroleum potential of sedimentary basins. Particular emphasis is placed on the thermal effect of intrusive bodies on organic matter and hydrocarbons. The principles of classification of sedimentary basins are presented based on the degree of maturity by the time of the most intense stage of trap intrusion. The foundations of the technique of calculation of the predicted hydrocarbon resources are given for the basins of different types.
