Abstract
Based on studies of the burial depth and the history of thermal variation of the Carboniferous in Tarium Basin, the present paper indicates that there was possibility of secondary petroleum generation in the carboniferous of the basin. The author suggest that oil reservoirs originated from the carboniferous may, in all probabilites, be found in the area, if only enough organic matter was preserved in the carboniferous, i.e,it was located in the so-called "preservation window", at the end of the variacian movement and prio to the uplift, and was present in "oil-gas window" at the time of or after the formation of structural framework. Moreover, in the light of the history of the structural of evolution of the basin, the time of formation of structures of various stages of the basin is analysed and the hydrocarbon potentiality of the area assessed.
