A field workshop of the International Geoscience Programme (IGCP) project 499 entitled ?Devonian Land ?Sea Interaction: Evolution of Ecosystems and Climate? (DEVEC) was held between May 14th and 22nd in San Juan, Argentina. The Devonian of the Precordillera, Mendoza and the San Rafeal Block are of special interest for the project due to the palaeogeographic and biostratigraphic importance in the Devonian Malvinokaffric Realm. A two-day symposium in San Juan was followed by excursions to Western Argentina covering stratigraphic sequences from Early to Middle Palaeozoic. The workshop was organized by colleagues of the Facultad de Ciencias Exactas, Fisicas y Naturales, Universitdad Nacional de San Juan, Instituto de Geologia ?Dr. Emiliano Pedro Aparicio (INGEO), Instituto Superior de Correlacion Geologia (INSUGEO), Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET), and the Facultad de Ciencias Naturales e I.M.L. Universidad National de Tucuman. The workshop was designed to provide participants with an introduction to the diverse and  tectonically complex geology in the Precordillera, Mendoza, and the San Rafael Block. The symposium was initiated with an opening ceremony, which includes welcomming addresses by the Dean of the National University of San Juan, Ing. Jorge A. Sisterna, and by one of the organizors, Dr. Silvio Peralta. Dr. Peralta also presented an overview of the regional geological setting and gave an introduction to the outcrops provided by fieldexcursions. Dr. Peter Königshof gave a short overview on the new IGCP guidelines and on the past activities and future perspectives of IGCP 499. The second day included oral- and poster-presentations with a special focus on facies development in different palaeogeographical settings as well as stratigraphy, sedimentology, and biodiversity of the Devonian in Argentina an elsewhere. Field excursions were preceded by scientific sessions held at the National University of San Juan. A 120-page abstract volume and a field guide book was published, edited by Guillermo Acenolaza, Maria del Milagro Vergel, Silvio Peralta, and Rafael Herbst.
