V41C:
The Tempo of Continental Flood Basalt Eruptions Posters


Session ID#: 8387

Session Description:
Continental Flood Basalt (CFB) eruptions play an important role in mass and energy fluxes between the mantle, crust, and atmosphere, and at least the last four mass extinctions are associated closely in time with CFB "main-phase" eruptions. However, a better understanding of the timing and rate of CFB eruptions relative to paleontological and geochemical markers of major biospheric disturbances is necessary to further progress in understanding possible causal relations, as well as achieving a more fundamental geodynamical and petrological understanding of the genesis of these extraordinary volcanic events. This session provides a forum for presentation of new results or reviews from diverse fields including geochronology, volcanology, petrology, geochemistry, paleontology, and geophysical and atmospheric modeling that bear on this theme.
