Geological and Petrographic features of Dzirula crystalline massif’s Sazano pegmatite field: This thesis considers the geology of the East part of Dzirula crystalline massif, especially the geology of the Sazano pegmatite field, Sazano district existing rock petrology, and their mineralogical features. Sazano pegmatite field mainly is composed of granitoids. The difference of this rocks is not such in chemical composition, or mineralogical association, but by differences in the structures. On Sazanos pegmatite field is observed different rock structures. The recognition, of Sazano field compose rocks, obtained through structures. The most common structure is – coarse graphic-pegmatite structure. Which is quite distributed. The second most common structure – is hypidiomorphic - gtanite structure. Fine-grained rocks are less proliferated and submitted by aplite and quartz-porphyry rocks. And there also occur such rocks which in petrographic description are described as transitive. In this thesis, is meet the Sazano field rock microsection description. Which rocks can be divided into five groups: Pegmatite, Granite, Aplite, Granite-Aplite (transitive), and Quartz-Porphyry.
