- •
Taimyr lavas are a northerly extension of the Siberian LIP.
- •
Taimyr lavas share similarities to Noril'sk lavas which precede the main stage volcanism.
- •
Taimyr intrusives share similarities to Noril'sk intrusions related to Ni–Cu deposits.
- •
The Taimyr intrusive activity is ~ 247 Ma narrowing the reported age gap.
- •
Magmas were derived by large degrees of melting of asthenospheric mantle and underwent crustal contamination.
