ABSTRACT
ABSTRACT: The presence and work of a group of Swedish and Finnish geologists, who visited Argentina since the last decades of the 19th century and during the first half of the 20th. century, is herein presented in a very synthetic way. Their activities represented a significant contribution to the geological and paleontological knowledge of the Argentine territory, mostly unknown from a scientific point of view at that time. Some of them, as O. Nordenskjöld, J.G. Andersson, Th. G. Halle and P.D. Quensel, produced significant advances through the discovery of new geological evidence in the different regions that they studied. Others introduced new methodologies through their work, as C.z. Caldenius, in the chronological investigation of glaciolacustrine deposits, or P. Hagerman, in the study of grain-size methods in sedimentology, as well as the correlation of well-identified volcanic tephra layers from San Carlos de Bariloche to Tierra del Fuego, as V. Auer did, or a new stratigraphic-structural geological scheme for the Fuegian Andes, as it was proposed by E.H. Kranck.
