Geology of the Ara-Cinca region, Spanish Pyrenees, province of Huesca : (with special reference to compartmentation of the Flysch basin)

Abstract

Geological investigations have been carried out from 1955 to 1968 in the Spanish Pyrenees, Province of Huesca, directed by Prof. Dr. M.G. Rutten (Geological Institute of the State University of Utrecht). Locations are indicated on Fig.I. These investigations resulted in a number of theses and papers which appeared in: Estudios Geol6gicos (Madrid) and Geologica Ultraiectina (Utrecht). The present thesis describes the geology of the Ara-Cinca Region. Fieldwork was done during the summers of 1964, 1966 and 1967. Simultaneously, Dr. E. ten Haaf and his students of the same Institute mapped the southerly bordering Eocene Flysch-zone, of which the Ara-Cinca Region is the most eastern part. Literature about the region studied is scarce and of a general nature only. More detailed, mainly structural, information has been given in unpublished reports of B.Sc. students of the Utrecht Institute who covered minor parts of the Ara-Cinca Region.
