摘要
•Gold mineralisation is associated with magmatic-hydrothermal transition processes.•Main orebodies formed during extensional tectonics (multi-scale pull-aparts).•Mineralisation is concomitant to normal faulting during late magmatic stages.•Granite emplacement, late magmatic stages and orebodies formed from 611 to 608 Ma.
