Livadi Mafic-Ultramafic Complex and its metamorphic basement, N.E. Greece
type: CreativeWork
description: Regional mapping of the Livadi area, lying west of Mt. Olympos in N.E. Greece, has revealed that the present tectonic juxtaposition of the Livadi Mafic - Ultramafic Complex and the metamorphic lithologies of the Pelagonian basement, results from an involved history of deformation and metamorphism. The Pelagonian basement comprises a sequence of psammitic and pelitic clastics, frequently of arkosic composition, and probably of Palaeozoic age. Granitic and, less commonly, amphibolitic intrusives are widespread, and the largest, the Livadi Granite, has been designated an Upper Carboniferous age by analogy with the Kataphygion Granite to the north (Yarwood, 1976). This igneo-sedimentary sequence is overlain by neritic carbonates of presumed Triassic-Jurassic age (Godfriaux, 1968). During Lower Cretaceous time, these lithologies were subjected to an upper greenschist-lower amphibolite grade metamorphism which resulted in the paragenesis of biotite, phengite, epidote, garnet hornblende, oligoclase and albite. It was associated with flattening, and the development of mylonitic zones and a strong L-S tectonite fabric. The shape of clastic pebbles deformed at this time indicate that the dominant strain was one of flattening, but that the greatest amount of finite distortional strain is located within the shear zones, where the deformation is constrictional. Subsequent to this event, but prior to the emplacement of the Livadi Mafic - Ultramafic Complex, deformation of the L-S tectonite fabric occurred about major fold axes oriented sequentially NE-SW and NW-SE, and resulted in the production of kilometre-scale interference patterns. Estimates of shortening across folds of the earlier phase vary between 40% and 45%. Fabrics associated with these fold periods are only locally important. The broadly cumulate stratigraphy of the Livadi Mafic - Ultramafic Complex comprises serpentinite and metamorphosed dunite, harzburgite, lherzolite and gabbro, which tectonically overlie the Pel…
