PY - PUBLICATION YEAR: 1950 LA - LANGUAGE: Spanish AB - ABSTRACT: An account of the geology of the site of the proposed hydroelectric plant on the Anchicaya river, Cauca valley, Colombia. The area is composed essentially of a tonalite intrusion, probably related to Cretaceous-Tertiary magmatic activity of the western Andes, and Precambrian-Paleozoic schists and quartzites. The igneous rock is highly resistant and impermeable, affording a suitable site for the dam and reservoir; the metamorphic rocks are impermeable, but their structure makes them less suitable for the construction of the proposed tunnels.

The ore is considered magmatic in origin and to have been intruded in the late stages of the hydrothermal processes which caused alteration.

Cretaceous beds are not known, but are believed to occur below the Tertiary.

The distinctiveness and wide geographic range of the fauna combine to make it important in stratigraphic correlation, but its value in this respect has been impaired by difference of opinion as to whether its age is middle Oligocene, as originally claimed, or upper Eocene. The seven papers in this symposium comprise the response to a circular requesting current opinions as to the age of the Hannatoma fauna. Different aspects of the age-relationships of associated mollusks and Foraminifera in Venezuela, Colombia, Ecuador and Peru are discussed. The authors conclude that the Hannatoma fauna occurs mainly in upper Eocene but locally in Oligocene beds.".
