GEOLOGIA STRATIGRAFICA

The goal of the course is to provide suitable knowledge and comprehension concerning the following topics: • principles of stratigraphy and basic elements of stratigraphic correlation • spatial and temporal analysis of the stratigraphic successions • relative dating methods and Geological Time Scale • execution of stratigraphic logs and elementary geological profiles
