| Contribution to hydrocarbon occurrence in basement rocks* | |
| *The article is presented in English. Generally considered as non-productive, the basement hydrocarbons reservoirs were for long time neglected by the exploration activity, however as a matter of fact in various areas of the world basement rocks represent important oil and gas reservoir. Hydrocarbons may be accumulated in any igneous, metamorphic or cataclastic rocks with secondary porosity (tectonic porosity and /or dissolution porosity). Basement cataclasites – fault related rocks, produced by brittle deformation at elevated strain rates - can develop an important secondary porosity. Cataclasis can overprint various igneous rocks and metamorphite and may play an important role in the final (total) porosity of the basement. Following the acceptance of igneous and metamorphic rocks as hydrocarbons reservoirs in various petroliferous regions throughout the world, the cataclasites can be considered aptly too to draw the attention of the exploration activity. Key words: hydrocarbons, reservoirs, basement reservoirs, igneous rocks, metamorphic rocks, cataclasites, fault related rocks, brittle deformation, secondary porosity, exploration activity. |
