Structural and geochemical ore-forming processes in deformed gold deposits: towards a multiscale and multimethod approach

Abstract Integrating structural control on mineralization and geochemical ore-forming processes is crucial when studying deformed ore deposits. Yet data are rarely acquired at the same scale: typically investigated from district to deposit macroscopic scales whereas described microscopic scale. The deciphering of a deformation–mineralization history valid every scale thus remains challenging. This study proposes multiscale approach that enables reconciliation information collected scale, applied example Galat Sufar South gold deposit, Nubian shield, NE Sudan. It gathers field laboratory by coupling classical petrological–structural with high-resolution X-ray computed tomography, electron back-scattered diffraction laser ablation inductively coupled plasma mass spectrometry mineralized sulfide mineral assemblages. demonstrates there linear expressed deposit. We highlight relationships between Atmur–Delgo suturing tectonics, microdeformation minerals, syn-pyrite recrystallization metal remobilization, liberation upgrading. Our contribution therefore represents another step forward in holistic field-to-laboratory for any other sulfide-bearing, structurally controlled type.
