Etudes mineralogique et geochimique des granitoides de la region de Collo

Abstract

The region of Cap Bougaroun is part of the Kabylie of Collo. Structurally the massif of Cape Bougaroun is integrated in the Maghrebian chain; it belongs to the internal domain and more precisely to the base Kabyle. The tertiary magmatic complex of the Kabylie of Collo is exposed in a metamorphic and sedimentary complex that participates in the formation of this structural edifice. The granites occupy a large surface of outcropping which cover almost the whole massif of Cape Bougaroun, it is the ""pericuminous granites with cordierite"". These granites are of a clear color, often porphyroids. The essential minerals are: quartz, potassium feldspar, plagioclases, biotite, cordierite and muscovite. Tourmaline, zircon, apatite and ilmenite are the accessory minerals.
