...Peter J. Pollard; Ekaterina Pelenkova; Ryan Mathur Abstract The Ak-Sug porphyry Cu-Au-Mo deposit is situated within the Altai Sayan region that forms part of the Tuva-Mongol arc of the Central Asian orogenic belt. The Ak-Sug intrusive complex is made up of a series of nested intrusions, including...

... is established. Analysis of the composition of the deposits suggests that in the Ordovician, the Ak-Sug zone of West Sayan belonged to one of the blocks of the Tuva-Mongolian microcontinent and was separated from other blocks, including the block containing the Tuva paleobasin. In the context of modern...
