Geological Setting and Ore Reserves of Gadir mineralization (Gedabek District) deposit, Azerbaijan, Lesser Caucasus

Abstract

The Gedabek district is one of the major porphyry-epithermal mineralization fields of Azerbaijan. The Gadir Au-Ag-Cu-Pb-Zn deposit is located in the east of Yogundag within the Shamkir uplift of the Lok-Karabakh suture zone in the Gedabek district of the Lesser Caucasus. The study area is composed mainly of the sequentially differentiated Lower-Upper Bajocian basalt-andesite-daciterhyolite rocks. Lower Bajocian volcanic and volcanic-sedimentary rocks emplaced in the geological structure of Gadir mineralization erupted in small outcrops of rhyolitic-dacite-containing subvolcanic bodies. In the region, the most significant fractures of tectonics are Gedabek-Bittibulag, Misdag and Gadir local orecontrolling faults of the northeastern, sub-latitudinal and northwestern directions. The Gedabek-Bittibulag fault is essentially the main ore-controlling structure that determines the position and location of deposits in the field. In this study, will give an outline of the detailed geological setting and brief reserve information of the Gadir Au-Ag-Cu-Pb-Zn deposit occurred at a low temperature although it is located quite close to the Gedabek high sulfidation Au-Ag-Cu deposit.
