Geodiversity consists of a new brunch of geosciences. It is derived from the environmental geology and it aims to proceed a whole study of the abiotic system that includes rocks, saprolite, landforms and soils. The research development in geodiversity starts in the last decade of twentieth century. It has generated encouraging results in geoconservation and territorial management studies in Brazil and all over the world. However, towards the consolidation of the landscape concept, so important to geography science, it is necessary to improve the geodiversity studies and techniques based on a multidisciplinary approach. This article proceeds to an epistemological evaluation of the concept of landscape and its theoretical and methodological importance for developing environmental geology and geodiversity studies. These guidelines accomplish the mission of CPRM – the Brazilian Geological Survey for geodiversity mapping of the whole Brazilian territory
