According to traditional classification accepted by Russian geologists, the largest unit of metallogenic zonation is «mineragenic province» identified as tectonic and geographical-economic domain with specific distribution of deposits. «Specific provinces» also called as «subprovinces» or «structural-mineragenic provinces-SMP» is a large block of earth crust, but a part of mineragenic province with specific type of deposits formed in specific time, typically during a tectonic cycle. In the Central sector of Russian Arctic the largest mineragenic units were formed during middle Mesozoic-Cenozoic cycle. According to this classification, Taimyr-Severozemelsky region covers parts of the following largest mineragenic provinces:

- The East Siberian ancient platform with Tungus-Lensky Riphean-Paleozoic oil and gas, Khatanga-Vilyui middle Mesozoic-Cenozoic oil and gas and Popygai Cenozoic impact-diamond SMP;

- Atlantic-Eurasian oceanic with Eurasian Cenozoic sulphide cooper SMP;
- Uralo-Mongolian folded belt with Western-Siberian middle Mesozoic-Cenozoic oil and gas bearing SMP;
- Verkhoyansk-Kolyma fold belt with Khatanga-Laptevomorsky late Mesozoic-Cenozoic potentially oil and gas, Verkhoyansk late Cimmerian polimetallic-fluorite-salt SMP.
-Novozemelsko-Taimyrsky folded belt with middle Mesozoic-Cenozoic Barentsevomorsk-Severokarsky oil and gas, Severotaimyr-Severozemelsky early Hercynian rare earths-gold and Taimyr coal-cooper-gold SMP.

On the scheme of structural-mineragenic zonation within the limits of SMP are allocated structural-mineragenic areas (SMA). For folded SMP their borders are subordinated to relicts of ancient tectonic-mineragenic complexes of specific cycles, for plate SMP - to rock associations with specific lithogeodynamic regime.
