GSRM Geological Formation Map of The Republic of Macedonia 1:500000

GEORM500k represents a simplified version of the geological map 1:500 000. Units are set aside in chronostratigraphic order. Mostly distributed are the old, prevailingly Pre-Cambrian formations which are raised eroded cores of megastructures. The old crystalline rocks are divided into lower and upper complexes . All rocks are metamorphosed under the conditions of amphibolites facies. Here are undoubtedly established Ordovician meta-sandstones, sericite schists and quartzites with marbles. The Mesozoic formations are comparatively less distributed. The Lower Triassic (sandstones, conglomerates, claystones and limestones) and Middle Triassic limestones can be found in Macedonia. The Jurassic and Lover Cretaceous have not been yet established in this area. Miocene end Pliocene sediments are mostly sands, clastics and pyroclastic. Regarding magmatic rocks granitoids, andesite-dacites and youngest basalts occur.
