Abstract: 

V. Vâlkov, N. Antova, K. Dončeva. The granitoids in Rila – West Rhodope batholith. The granitoids of Rila-West Rhodope batholith form the core of Rila-Rhodope dome - a large arch-block structure in the West Rhodope block. The configurati on of the dome is nearly isometric, slightly elongated in meridional direction. The batholith intrudes unconformably rocks of supposed Precambrian age, affected by repeated regional metamorphism in amphibolite facies.
   On the basis of petrographic, petrochemical and structural features, as well as of contact relationships, four phases of different age are distinguished: granodiorites (first phase), medium- to coarse grained biotite granites (second phase), fine-grained granites to plagiogranites (third phase), and aplitoid-pegmatoid granites (fourth phase). The granitoid magmatism is of polyphase character and is related to several tectonomagmatic phases.
