The Rhodope Metamorphic Complex is a stack of allochthons assembled during obduction, subduction, and collision processes from Jurassic to Paleogene and overprinted by extensional detachment faults since Middle Eocene. In the study area, the followin

Of the four superposed tectonic units in the study area, the uppermost (Unit IV) is lithologically similar to the lowermost (Unit I). Both are formed dominantly by orthogneiss. In an earlier article, Bonev et al. (2010) had shown that the orthogneiss

Geochemistry of migmatite-granite connection: a case study from the Central Rhodope, Bulgaria

Autor: Emilia Raeva, Zlatka Cherneva

Publikováno v: Geologica Balcanica. 37:53-59

Extensive crustal melting and intrusive granite magmatism accompanied the extensional stage of the Rhodope massif Alpine evolution. Granites of different structural position and time of crystallization could reveal compositional and temporal relation

High-pressure garnet-bearing migmatites from the Chepelare area, Central Rhodope

Autor: Zlatka Cherneva, Milena Georgieva, Elena Stancheva, Ianko Gerdjikov

Publikováno v: Geologica Balcanica. 37:47-52

The association of Ca-rich garnet and Na-rich plagioclase in migmatites is a proper indicator for high-pressure melting. Garnet-bearing leucosome and aplitoid gneiss from the Mechi Chal peak in the Chepelare area of the Central Rhodope comprise a min

Metamorphozed Hercynian granitoids in the Alpine structures of the Central Rhodope, Bulgaria: geotectonic position and geochemistry

Autor: Milena Georgieva, Zlatka Cherneva

Publikováno v: Lithos. 82:149-168

Orthogneisses of late-Hercynian protolith age crop out in the Central Rhodope high-grade metamorphic complex, which is part of the Alpine orogen in south-eastern Europe. They compose a tectonic unit bordered by late-Alpine extensional shear zones. Th

The monazite Th–Pb chronometer is widely used in a variety of geological contexts but may be affected by interaction with fluids. In the central part of the Rhodope Massif (Greece, Bulgaria), synfolial pegmatite veins were emplaced within two major
