Abstract

In this study geological and geomorphological remote sensing investigation methodologies were applied to define the role of tectonic and neotectonic features in controlling the evolution of the Triest Karst territory, located at the Italian- Slovenian border. A Landsat TM image of the study area, has been visually interpreted using different products, with different information content, resulting from standard processing, in order to recognize main textural and structural characteristics of the area. The processing was aimed to enhance morphological (drainage networks, landmass denudation stages) and structural features (lineament pattern), as well as to identify main land-systems. Morphological, structural and landform elements were integrated to define some geomorphological-structural units having their own specific attributes. Structural trends have been recognized by means of rose diagram representations of lineament azimuth-frequency and cumulative-length distributions. Analysis of lineament frequency data, performed individually one each geomorphological-structural unit and on the study area as a whole, reveals that structural trends are strictly unit- dependent, and generally in agreement with regional structural models and focal mechanisms solutions reported in literature, with NE-SW dominant meso-alpine thrust faults reactivated with transpressive components during the neo-alpine phase and with more relevant dextral strike-slip movements recently, consistently with a NNW movement of the subthrusting Adria Plat, and an hypothetical counterclockwise rotation of the Istria peninsula.
