Geological journal| Zusammenfassung: | In this article intrusive-magmatic genesis of Demuryno complex is substantiated based on the following data: sharp, active contacts with the host rocks, the presence of endo- and exoalternations in contacts, simple and relatively homogeneous rock composition of rock massives, eutectic character of crystallization of porphyraceous granitoids, directive trachytoidic structure of rocks and other features. On the base of research results it is proposed to update the current Chronostratigraphic Correlation Scheme of the Early Precambrian of the Ukrainian Shield and include Demuryno intrusive complex to the group of intrusive complexes in the range of porphyraceous granites and granodiorites formation. |
