This is the second issue of Geologica Acta dedicated to the memory of Professor Francesc Calvet, who passed away in January 2002. Francesc was a man with great human qualities, a distinguished scientist and an inspiring teacher who was held in high esteem by all those who knew him. The first volume contained six papers on specific areas of research in which Francesc was engaged, and a biography (Geologica Acta, volume 2, Nº 4, 2004). This second volume is made up of contributions by colleagues and former students who wish to salute Francesc Calvet as an outstanding geologist and teacher. The papers included in this volume are also subjects in which Francesc was closely involved.
