Includes the following symposia:
6.2. Deccan volcanism and its role in mass extinction and paleobiodiversity
Convenors: Gerta Keller (gkeller@princeton.edu), N Malarkodi (nallamuthumalarkodi@gmail.com)
Extinction events are important factors in the history of life on Earth, and many studies suggest catastrophic causes for at least some major mass extinctions. Two types of catastrophic event have been invoked: major impacts by asteroids or comets and episodes of continental flood basalt volcanism. Of the five major mass extinctions in Earth’s history, only the Cretaceous–Tertiary (K–T) mass extinction has been positively linked to an asteroid impact/ continental flood basalts (CFB), Over the past decade continental flood basalts (CFB) have been correlated with most major mass extinctions leading to suggest that this may be the general cause of mass extinctions. The symposium will cover various aspects on volcanism and its role in mass extinction and paleobiodiversity and the key note addresses are arranged besides technical sessions.
16.1. Large igneous provinces and their plumbing systems
Convenors: Rajesh Srivastava (rajeshgeolbhu@bhu.ac.in), Richard Ernst (richard.ernst@ernstgeosciences.com)
This symposium intends to discuss the temporal and spatial distribution of LIPs, their origin and links to mantle plumes, mafic dykes and dyke swarms, superplume events, supercontinent reconstructions, climate changes (including mass extinctions) and associated metallogeny.
