Three one-day field trips. Orientation in the field, usage of topographic - geologic maps and compass; identification in the field and interpretation of simple geological concepts: layers, strikes and dip direction of rocks; differences between metamorphic and non metamorphic sedimentary rocks; litho- and bio-phases; in situ interpretation of basic geological map elements (lithological, stratigraphical units and contacts), measurement of folds, microfaults, fissures, cleavages (geometry, interpretation and origin models) in metamorphic rocks of different lithology (marble, quartz, schists).
