Kadyross is the largest massif of East Tuva covering about 150 km2 and, according to Makhin and Pavlenko (1966), the combined occurrences of Kadyross and Kyshtag cover more than 250 km2. Kyshtag lies several kilometres to the northeast of Kadyross. Peralkaline syenites are extremely abundant and peralkaline and calc-alkaline granites are common in the eastern part of the complex. There are granite dykes and veins, syenite porphyry, peralkaline syenite pegmatite and aplite.
