The VICCO talk is helt by: Jun Shen, Professor at China University of Geosciences, Wuhan, China, and has this title/topic:
The basalt weathering effect to the climate and environmental during the Paleozoic-Mesozoic transition
Abstract:
Massive volcanism, particularly from Large Igneous Provinces (LIPs), is generally thought to have triggered significant earth habitability perturbations, such as disruptions in surface climate, environmental conditions and biological evolution and extinction throughout Earth’s history.
While the effects of volcanic volatiles have been extensively studied, the impact of subsequent weathering of large amount of volcanic rocks (e.g., basalt) on surface elemental cycling, climate fluctuations, and biological evolution remains less understood, particularly also regarding the timescales involved in these processes. This study, I will present the geochemical data of the sediments to track the basalt weathering effect to the climate as well as environmental variations for the low latitude Emeishan (ELIP) and high latitude Siberia Trap large igneous province (STLIP).
Our results show that beside the tropical basalt (ELIP), the high-latitude basalt (STLIP) weathering under extremely higher temperature intervals could also play significant role to the earth habitability up to tens of millions of years after the eruptions in the Early Triassic.

About the VICCO+ seminar series
The seminars are open for everyone interested, and especially students are welcome. The talks in VICCO+ seminar series are offered by the The VICCO centre, Dept. of Geosciences, University of Oslo.
The VICCO+ talk seminar series are normally held in the Geology Building, at UiO's campus Blindern, see this map.
The Co-ordinator for the talks is
