The element of stratigraphy that deals with the description and nomenclature of the rocks of the Earth based on their lithology and their stratigraphic relations. 2. Lithostratigraphic classification. The organization of rock bodies into units on the basis of their lithologic properties and their stratigraphic relations.To understand the interaction between society, geodiversity and the biotic nature, our methodology builds upon the Guide- lines for geoconservation in protected and conserved areas by the IUCN, an international framework. For this, we have established three key stages. The first stage entails an overview of the region’s geodiversity, providing a …
