  • CORE

    Epithermal gold occurrences related to Quaternary volcanics are being intensively studied for their precious metal potential. Adularia-sericite type occurrences have been found. Analyses of 579 core and cutting samples collected for exploratory geothermal studies from a number of localities (Gedemsa, Aluto and Corbetti calderas, and the Tendaho graben, Afar) were analyzed for gold.

    We investigate thermo-mechanical properties of the crust in the northern Main Ethiopian Rift (MER) by analyzing the interrelationships between the depth distribution of seismicity, geothermal gradient, composition, and crustal strength, We use both hypocentral depth as well as moment magnitudes of 2000 well constrained earthquakes from the EAGLE catalogue (2001-2003) with +/- 2 km hypocentral

  • First evidence of epithermal gold occurrences in the SE

    The geology of the Republic of Djibouti, in the SE Afar Triangle, is characterized by intense tectonic and bimodal volcanic activity that began as early as 25-30 Ma. Each magmatic event was accompanied by hydrothermal activity. Mineralization generally occurs as gold-silver bearing chalcedony veins and is associated with felsic volcanism.
