This paper is an abstract of a more comprehensive work published in the memoires de l'Academie royale de Belgique (J. Michot, 1961). It records information obtained from geological researches carried out in the Egersund area (southwestern Norway) from 1952 to 1958 during six successive summers, each of five or six weeks. The material collected during the field work was studied at the University of Liege (Belgium) in the department of Geology, Petrology and Geochemistry directed by Prof. P. Michot.
