Study of solid natural hydrocarbons is of great theoretical and practical importance. On the one hand, their industrial accumulations may be considered a nontraditional raw-material source for chemical industry. On the other hand, they permit us to solve problems on formation of by-products of naftidogenesis. In this paper we describe hard bitumens ("pyrobitumens") localized within dolerite sills and report evidence of the destructive-sublimation character of their formation simultaneous with sill genesis in the Minusa intermontane trough.
