Since 1945 Estudios Geologicos publishes original research works, as well as reviews, about any topic on Earth Sciences.

Estudios Geologicos is published as one yearly volume, divided into two half-yearly issues. It is edited by the Spanish National Research Council (Consejo Superior de Investigaciones Científicas, CSIC) at the Instituto de Geociencias (CSIC-UCM).

Estudios Geologicos provides free access to full-text articles through this electronic edition. Accepted articles appear online as "Forthcoming articles" as soon as the galley proofs have been approved by the authors and the Editor-in-Chief. No changes can be made after online publication.
