In this study, we investigated the Zicavo Metamorphic Complex (southern Corsica), which ispart of the innermost Axial Zone of the Corsica-Sardinia Variscan belt. To better evaluate itsgeological and structural outline, a 1:5000 geological map, coupled with new structural/microstructural and petrographic data, is presented. The complex is formed by threetectonic units, from bottom to top: (i) an Orthogneiss Unit, (ii) a Leptyno-Amphibolite Unit,and (iii) a Micaschist Unit. They are separated by ductile shear zones with a top-to-the-SEsense of shear. They underwent a polyphase deformation and polymetamorphic history,with a shortening stage in the amphibolite facies, responsible for the main structures andshearing, followed by an exhumation phase.

Abstract

In this study, we investigated the Zicavo Metamorphic Complex (southern Corsica), which ispart of the innermost Axial Zone of the Corsica-Sardinia Variscan belt. To better evaluate itsgeological and structural outline, a 1:5000 geological map, coupled with new structural/microstructural and petrographic data, is presented. The complex is formed by threetectonic units, from bottom to top: (i) an Orthogneiss Unit, (ii) a Leptyno-Amphibolite Unit,and (iii) a Micaschist Unit. They are separated by ductile shear zones with a top-to-the-SEsense of shear. They underwent a polyphase deformation and polymetamorphic history,with a shortening stage in the amphibolite facies, responsible for the main structures andshearing, followed by an exhumation phase.
