Crystalline Protrusion as the Typical Structural–Tectonic Model of Intragranite Hydrocarbon Accumulation

Resumo

The paper deals with issues related to the study questions on magmatic tectonics and intragranitic hydrocarbon accumulating formation: (i) post-magmatic structure of granitic massifs containing hydrocarbons; (ii) mechanisms of structure-material processing, exhumation and forming porosity in granitic bodies on post-magmatic evolutional stage; (iii) availability and distribution of hydrocarbon deposits in granitic massifs located in different geodynamic settings and different regions; (iv) description of crystal piercing bodies ‒ granite protrusions. The role of structural tectonic factor in intra-granitic hydrocarbon accumulating was estimated. An evolutionary structural-tectonic model of their formation within granitic massifs and, above all, granitic protrusions is proposed.
