“…suggest the Permian age of this formation (Meyen, 1966;Sadovnikov, 1987b;Mogucheva and Naugolnykh, 2010). The Ivakin Formation correlates with the upper Tailugan and lower Maltsev formations of the Kuznetsk Basin the late Permian ages of which recently were established with CA-IDTIMS dates (Davydov et al, 2021). The Ergalakh intrusive sill complex (Figure 3) has been proposed to be a feeder of the volcanism of the Ivakin Formation (Ryabov et al, 2001;Rad'ko, 2016;Latyshev et al, 2019).…”

“…This taxon is considered as the index of the Induan Stage in continental facies (Schneider et al, 2019). The Tutonchanian RS in the Central Tunguska Basin and Kuznetsk Basin is characterized by a similar flora and fauna and directly correlates with the Tutonchanian of the Norilsk region (Vladimirovich, 1967;Betekhtina et al, 1986;Dobruskina, 1994;Sadovnikov, 2008;Mogucheva, 2016;Davydov et al, 2021).

“…The late Permian Euromerian flora in the Northern arid belt along the northern slope of the Variscan orogenic belt (Germany, France, Caucasus) was predominantly xerophytic suggesting relatively warm and dry climate with no coal accumulation (Chumakov and Zharkov, 2003;Roscher and Schneider, 2006;Naugolnykh, 2007). The climate in the Angaran Realm was temperate and very wet with abundant coals that occur up to the top of the middle Changhsingian (Figure 2) (Cherepovskiy, 2001;Dobruskina and Durante, 2004;Davydov, 2021;Davydov et al, 2021). The upper Permian in the Kuznetsk Basin possessed the thickest coals (wet environments) in the entire Siberia (Cherepovskiy, 2001).…”

“…The major climate change occurs in Tunguska and in the Kuznetsk Basin sometimes during the second half of the Changhsingian, around 252.75 Ma (Davydov et al, 2021). At this time, the biomes differentiation is sharply decreased and the Euramerian --Angaran Realms boundary shifted northward approximately to 15 °.…”

The end-Permian extinction event (EPEE) considered to have been caused by the eruption of the Siberian Large Igneous Province (SLIP), the age of which is critical for extinction-SLIP model evaluation. The Tunguska Basin flora during this time, in accordance with the EPEE model, supposed to have been killed by the massive injection into the atmosphere of poisonous substances such as methane, sulfates, mercury and massive combastion of coals. In addition, supposed numerous fires presumably devastated the regional flora. However, the diversity of the Tunguska Basin flora drasticly increased at the beginning of Induan or slightly earlier and become diverse at the species level in the Olenekian and Anisian, when the main phase of basalt eruption and associated intrusive activity occurred. The overall magmatic activity during the latest Permian and Early Triassic did not kill the flora, but rather stimulate their diversity. The geomagnetic secular variations from the intrusions revealed the similarity of paleomagnetic directions of the Norilsk group layered intrusions with those of the upper Olenekian and lower Anisian Mokulaev and Kharaelakh volcanic formations and intrusions of the Talnakh group with the Olenekian Moronga-Mokulaev formations. The U-Pb dates and the geomagnetic secular variations data expose the obvious discrepancy between these two datasets. The paleomagnetic data suggest that the Norilsk-1 intrusion is younger than the Talnakn and Kharaelakh intrusions, but the U-Pb dates indicate the opposite. The data from layered intrusions in Norilsk and the other regions suggest their prolonged duration and multi-stadial formation. The U-Pb dates from the intrusions of the Norilsk region roughly constrain the onset of the SLIP and generally postdate the end-Permian extinction.
