The paper does not discuses about the term of geosite or its definitions. Those aspects are already well known for the scientific researchers. In the last years, some intense scientific activity was concerned to releasing papers which the main subject was the geosite and his derived terms: geomorphosite, geoarcheological sites etc. We can see a scientific boom around this notion. In those conditions it is necessarily to make a theoretical work with the scope to introduce the lecturer in the complexity and interdisciplinary properties ofthis research field. The paper starts with a short history of the development of the field and continues with his most important component: the geomorphologic site and some perspectives to valuing. Finally, we note that the anthropic monument can be analyzed as geosites too, and the best way to make a cartographic representation of geosites is to use the GIS solutions.
