| Tartalmi kivonat: | One of the most important rock groups outcropping in the NE part of the Ditró Massif, north of the Orotva (Nagyág) creek and from the Török creek to the crystalline schists is the group of the granitic rocks. On the basis of their modal composition and textural features, this rock group can be divided into the following rock types: 1. syeno- and monzogranites with equigranular texture; with potassium feldspar megacrystalline texture, alkaline granites. 2. syenites, quartz syenites, alkaline syenites, foidic monzosyenites. 3. monzonites, quartz monzonites. 4. cataclasites. On the geological maps of 1:10.000 scale the granitoid formations were shown as a homogeneous body. Our studies have revealed that petrography of this area is much more complex than it was interpreted by the former studies. On the basis of the textural studies, it has been concluded that secondary textural patterns of the rock types are similar, and it can be attributed to endomagmatic effect, weathering processes and tectonic deformation. |
