Abstract

The map of the coastal area between cap Trahili and cap Trekala (34 58‚ 00‰ the latitude North and 24° 54' 18 - 24° 58' 00 longitude East) is presented (1:10,000 scale map). The survey map is the sheet 1:5.000 of the Greek M.G.S., and the preliminary geological cartography was made using the Geological sheet 1:50.000 scale map, by Greek geological institute with the aerial photos interpretation (flight B/W, 06.15.1995, 1: 8.000 scale map by Aeronautics Greek service) integrated by the survey effected on the field during the 2002 e 2003 Kriti expedition. It is aimed mainly at locating and mapping the marine and transitional terraces in south Kriti coast. From a methodological point of view, we followed the general criteria internationally adopted in coastal geological cartography. Considering the scale of the map and the difficulty in finding complete and uniform preliminary cartography, this work is different from the quoted bibliographical references, both in its legends and in some of the graphics related to practical requirements of the studied area. For some aspects (eg: graphics, explanations, information) the map is innovative especially as regards the use of digital data, low production costs and easier readability. Cartographic restitution is prevalently referred to the coastal belt and reports the littoral, eolian, lacustrine and slopes forms, processes and deposits as well as those due to the flow of surface water or to the present coastal dynamics. Moreover, with the help of photos printed at the edge of the map, the main geomorphological units are described: The show map extension the presence in outcrop of a geologic substrate with age comprised between the Mesozoic (Jurassic) and the Holocene on it has been recognized a series at least four main orders of marine terrace (from o to 25 metres above present sea level) represents from old palaeoabrasion platforms or palaeo beach deposits constituted from fossiliferous sands and gravels.
