Major and trace elements in orthoamphibolites from the Central Rhodope Mts

pp. 25-30

Amphibolites from subintrusive and bedded bodies belonging to the Lukovica Formation oi the Rhodope Supergroup in the Northern-Rhodope Anticline are fully characterized chemically and are divided into three groups: high-aluminum, high-iron and high-chromium amphibolites. Their petrological features and major element composition as well as the contents and distribution patterns of trace elements are found to resemble closely those of the basic magmatic rocks of tholeiitic character.
