Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia by Mackay, Anson W., Seddon, A.W.R., Leng, Melanie J., Heumann, G., Morley, D.W., Piotrowska, N., Rioual, Patrick, Swann, George E.A.

“…The forest–steppe ecotone in southern Siberia is highly sensitive to climate change; global warming is expected to push the ecotone northwards, at the same time resulting in degradation of the underlying permafrost. …”

Phanerozoic mafic magmatism in the southern Siberia craton: geodynamic implications by Gladkochub, D., Donskaya, T., Ivanov, A., Ernst, R., Mazukabzov, A., Pisarevsky, Sergei, Ukhova, N.

“…The Late Paleozoic event (∼275 Ma) produced dikes that intruded in a setting of subduction-related extension at the back of the active continental margin of Siberia during closure of the Mongolia–Okhotsk ocean, as well as slightly older volcanics (290 Ma) in the Transbaikalian segment of the Central Asian orogen. …”

Spatial differences in dissolved silicon utilisation in Lake Baikal, Siberia: examining the impact of high diatom biomass events and eutrophication by Panizzo, Virginia, Roberts, S., Swann, George E.A., McGowan, Suzanne, Mackay, Anson W., Vologina, Elena, Pashley, Vanessa, Horstwood, Matthew S.A.

“…Recent research has highlighted how Lake Baikal, Siberia, has responded to the direct and indirect effects of climate change (e.g., ice-cover duration), nutrient loading, and pollution, manifesting as changes in phytoplankton/zooplankton populations, community structure, and seasonal succession. …”

U-Pb detrital zircon geochronology and provenance of Neoproterozoic sedimentary rocks in southern Siberia: New insights into breakup of Rodinia and opening of Paleo-Asian Ocean by Gladkochub, D., Donskaya, T., Stanevich, A., Pisarevskiy, Sergei, Zhang, S., Motova, Z., Mazukabzov, A., Li, H.

“…Before the break-up of Rodinia and opening of PAO, Tonian – Cryogenian intracontinental sedimentary basin existed between southern Siberia and northern Laurentia. The detachment of the southern flank of the Siberian craton from northern Laurentia and opening of the PAO between these cratons took place in Cryogenian. …”

Mesoproterozoic intraplate magmatic ‘barcode’ record of the Angola portion of the Congo Craton: Newly dated magmatic events at 1505 and 1110 Ma and implications for Nuna (Columbia)... by Pisarevsky, Sergei, Ernst, R., Pereira, E., Hamilton, M., Rodriques, J., Tassinari, C., Teixeira, W., Van-Dunem, V.

“…The combined presence of both 1505 Ma and 1380 Ma magmatism in the Congo–São Francisco reconstructed craton is a match with similar ages published for two intraplate magmatic provinces in northern Siberia and suggests a nearest-neighbor relationship in the supercontinent Nuna in which northern Siberia is juxtaposed adjacent to the western São Francisco portion of the reconstructed São Francisco–Congo Craton.In addition, a precise U–Pb TIMS baddeleyite age of 1110 ± 2.5 Ma was obtained for a prominent NNW–NNE trending gabbro-noritic (GN) dyke swarm in southeastern Angola, but this age is currently unknown in Siberia suggesting that the breakup of Congo–São Francisco Craton from Siberia happened earlier, perhaps in association with the 1380 Ma event. …”
