ABSTRACT: This paper describes field mapping and structural analysis of the Aburna gold district to identify the structural controls on gold mineralization. The study links NE-trending shear corridors, quartz-carbonate-sulphide vein generations, and silica flooding to an orogenic gold system developed within a dextral transperssional setting. The main conclusion is that gold is concentrated in subsidiary shear zones within a broader regional Dextral shear framework. The structural data indicates that regional dextral shearing was responsible for a low rank dextral shear system. Subsidiary dextral shear systems create critical ore depositional space through a combination of shear extension and compression.
