...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...

Sampling for spore-pollen analysis was from silt layers in glaciofluvial facies (Lower Chaindy outcrop), from rhythmic sand-silt-clay deposits of the Ak-Sug outrcrop, and the lower part of the Kara Khem outcrop, at every 10–15 cm. The samples were...

No core samples from the site being available, we used thermal conductivity data from the Ak-Sug site ( Fotiadi, 1987 ) located 10 km east of Aryskan where average thermal conductivity of pla-giogranite and tonalite was 3.5 W/m.K, over 30 samples...
