In central Rhodope of northern Greece, kyanite eclogites were discovered in the area of Thermes. They are strongly overprinted and exhibit a multi-stage development of minerals and mineral assemblages formed during successive stages of the exhumation. The initial high-pressure assemblage was garnet+omphacite+kyanite+zoisite+phengite+rutile+quartz. Corundum, Fe-Mg-spinel, sapphirine and hogbomite occur as products of a first, high-temperature overprint, still at high pressures, whereas various symplectites [corundum-plagioclase (pi), spinel-pl, sapphirine-pl, clinopyroxene-pl, biotite-pl, amphibole-pl] grew during subsequent stages of the exhumation. Diablastic amphibole+plagioclase formed as end-products of the amphibolitization. According to geochemical data, the protoliths of the kyanite eclogites were basalts to basaltic andesites with ''volcanic arc'' affinities. For the high-pressure stage of metamorphism, minimum PT conditions were around 19 kbar, 700 degrees C, while for the initial stages of the overprint? high-pressure granulite-facies conditions prevailed (T>800 degrees C, at P>15 kbar). The PT conditions of the amphibolite facies were 8-11 kbar, 580-690 degrees C, The kyanite eclogites of Thermes record the highest temperatures of metamorphism within the whole of Rhodope.
