Direction of material creep during the deformation phase in shear zones, role in mining prospecting: A case of the Nassara-Torkera gold deposits in the Gaoua region, Burkina Faso, West Africa

Mineralization at the Nassara and Torkera gold deposits is situated at the contact between volcanic rocks (basalt-andesite) and volcanosedimentary rocks (pyroclastite, black shale) within the echelon faults of the large West Batié shear zone (WBZ). Along the mineralized body, shear deformation is intense, accompanied by significant hydrothermal fluid circulation. The objective of this study is to determine the...
