Birth of the Dalradian Supergroup and its path through Neoproterozoic Earth history

Professor Tony Prave, University of St Andrews

The most enduring concept of the Dalradian Supergroup is that it formed during a prolonged phase of extensional tectonism, starting with breakup of the supercontinent Rodinia and ending with the opening of the Iapetus Ocean. This evening Tony will revise and refine that concept, integrating the Dalradian’s rock record into the geological and environmental conditions recognised currently as those that define the latter half of Neoproterozoic time worldwide.

Tony’s research uses field-based observations and isotope geochemistry to create, test and constrain ideas about the processes that shaped Earth’s surface environments. He is particularly interested in those pivotal times of geological history during which wholesale Earth system change occurred. Tony has been awarded the Edinburgh Geological Society’s Clough Medal for 2023-2024.
