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.
