Geología de la isla de Branco (Cabo Verde)

Abstract

The morphological, structural and volcanological aspects of Branco, an island of the Cape Verde Archipelago, are described and interpreted in this work. The isle consists of a 700 m thick pile of basalt lava flows and scarce pyroclastics crossed by several families of dikes. The structure of the island could correspond to the remaining fragment of a primitive large shield volcano. The main hypothetical emission centre could once be situated between the present islands of Santa Luzia and Branco.
