Abstract
The Hoggar Shield is one of the most ancient geological objects of Algeria. It is made up of the Archean, Lower Proterozoic and Riphean-Vendiangranitoids, and metamorphosed volcanogenesedimentary rocks. The main tectonic elements of the Shield are horst-anticlinoria and dividing them graben-sinclinoria.The age of their formation is about 760-600 millions years. Gold ore mineralization is connected with hydrothermal veins of different age, origin and mineral composition. Five types of auriferous veins have been defined according to these criteria.
