Abstract

A detailed geological and petrographic study of the Upper unit, 'Unita Superiore', the highest tectonic unit outcropping in the Aspromonte area of S Italy, has been carried out. This unit, consisting of Hercynian metamorphic rocks with a Mesozoic carbonate cover, outcrops around Montebello Jonico, Roccaforte del Greco, San Lorenzo and in a large body near Palizzi Marina and in a few small klippen as far as the village of Staiti. They overlie tectonically the Aspromonte unit, which is composed of medium-high-grade gneisses and amphibolites intruded by magmatic rocks. The tectonic contact, evident in many exposures between the Valanidi stream and Staiti, cuts the schistosity of both units and is characterized by decimetric bands of cataclasites. The 'Unita Superiore' consists mainly of clastic deposits belonging to several sedimentary cycles, with ages ranging early Miocene-Pleistocene. The Hercynian metamorphic history, as observed in biotite paragneisses and mica schists, is characterized by four blastic phases: the first and third were dynamic and the second and fourth static.-J.M.H.
