“…In Crete, the shape of strain ellipsoid varies from flattening via plane to prolate (Fassoulas et al, 1994;Zulauf et al, 2002). 3D strain data from north Peloponnese show slightly constrictional to plane strain conditions, with k being approximately 1.4 .…”

“…Numerous kinematic indicators such as quartz c-axis fabrics, oblique grain shape fabrics, asymmetric boudins, sigma-shaped porphyroclasts, bookshelf tiling of HP-related minerals, S/C fabrics and single sets C'-type shear bands indicate a clear top-to-the-west (Peloponnese and Kythira) top-to-the-south (Crete) shear sense (Xypolias and Koukouvelas, 2001;Zulauf et al, 2002;Chatzaras et al, 2006). Evidence for top-to-the-east (or north) shearing (backward motion) has been mainly found at the upper structural levels of the PQ unit.…”

“…Based primarily on overprinting criteria observed in map to outcrop scales as well as on microstructural data, three principal ductile deformation phases (D 1 -D 3 ) have been distinguished to constrain the structural evolution of the PQ unit (Greiling, 1982;Doutsos et al, 2000;Fassoulas et al, 1994;Zulauf et al, 2002;Kokkalas and Doutsos, 2004;Chatzaras et al, 2006;Xypolias et al, 2008).

“…The age of these rocks is considered as Upper Jurassic to Oligocene, and their appearance in the area is restricted only at its northeastern part and especially in Cavo Sidero cape. The Phyllite-Quartzite nappe consists of pre-alpine and alpine in age, metamorphic rocks of blueschist to greenschist phases metamorphism and is tectonically posed upon plattenkalk rocks (Franz, 1992;Zulauf et al, 2002). Apart from metamorphosed, the rocks of this unit are also very intensely tectonised.…”

In the present document we present the main studies, actions, initiatives and infrastructure developed under the project GEOTOPIA aiming to develop a geopark at the easternmost part of Crete, in Sitia area. The developed activities may be considered as model to establish a geopark in a rural area under the provisions of European and Global Geoparks Networks, aiming intimately to a responsible tourist development. Study area includes the eastern coastal zone of Sitia municipality extended westwards to the Sitia mountains. It presents an impressive geological heritage constituted mainly by the landscape variations (including gorges, plateaus and long cave systems), hydrological resources, rock types and abundant mammal fossils. The project resulted in an inventory, mapping and evaluation of geotopes using existing methodologies, in undertaking conservation, educational and geotourisitc activities, among them the development of two educational projects, two local museums, 15 geotrails, outdoor panels and signposts, as well as printed, visual and web material. A management and action plan has been also conducted presenting the goals, the methodologies, the resources and the timetable to manage the area as a real geopark. Furthermore, the plan foresaw the interaction of geopark initiative in respect to other planned investments and activities in the area.

New kinematic and structural data from the tectonic windows of eastern Crete and the Dodecanese Islands combined with strain and quartz fabric analysis have enabled us to determine a detailed structural evolution of the region and to present a plate tectonic scenario for the southeast Hellenides.During the Early Mesozoic, the southeastern part of Apulia was separated from North Africa and the adjacent microplates by WNW-trending rift zones and NE-trending transfer faults. Displacement along the transfer faults has locally reoriented these rift zones into an ENE-WSW direction. Finite strain and quartz fabric asymmetry data indicate that in Late Cenozoic time, NNWdirected nappe movements caused a nearly coaxial deformation along the ENE-WSW trending rift segments and non coaxial top-to-the-southeast shearing along the WNW-trending rift segments, as well as along the pre-existing NE-trending transfer faults. Tectonic style along the margin varies in response to the obliquity of the principal shortening direction with respect to the margin. These variations could be due to the pre-convergence geometry of the southern margin of Eurasia and to local strain partitioning effects.Furthermore, a tectonic model is presented in which syncompressional uplift and vertical buoyancy of the subducted crustal slice caused the rapid exhumation of metamorphic units in the south Hellenides.
