The features of earth’s crust structure have been studied, continental rifts with typical<br>sings of development have been discovered geophysical fields, differing with structure, continental crust<br>thickness and heat degree of bowels. Regularity of hydrocarbon fields forming with high resources density in<br>zones of oil-gas accumulations combined or conjugated with regional centers of oil and gas generation of<br>riftogenous regime had been defined.
