The Rhodopian collision includes diverse sediment source areas associated with arc-continent collision during closure of the Vardar ocean basin and subsequent accretion along the southeastern margin of European plate. Accretionary processes involve Paleozoic metamorphic rocks, mostly phyllite, schist, amphibolite and gneiss, and Mesozoic ophiolitic rocks of the Vardar oceanic basin. The volcanic arc, located on the European margin, consists of dominantly andesitic volcanics and related plutonic rocks.
The petrography, as well as major and trace element composition of 135 sandstones samples from the Eocene to Oligocene strata located in the area between the greek Thrace, NE Greece, and SE Bulgaria have been investigated. This talk will discuss the provenance of the sandstones and the relationship between the sedimentary environments and rock compositions.
