Serpentinite in the Earth System

Discussion meeting

Location

The Royal Society, London, 6-9 Carlton House Terrace, London, SW1Y 5AG

Overview

Scientific Discussion meeting organised by Dr Andrew McCaig, Professsor Peter Kelemen, Dr Gretchen Früh-Green and Professor Damon Teagle

This meeting will bring together international scientists working on all aspects of serpentinisation, a process that may have been important for the origin of life on Earth and perhaps other planets. Serpentine is also a key carrier of water to depth in subduction zones, leading to intermediate depth earthquakes and the formation of island arc volcanoes.

The schedule of talks and speaker biographies are available below. Recorded audio of the presentations will be available on this page after the meeting has taken place. 

Attending the event

This meeting is intended for researchers in relevant fields.

  • Free to attend
  • Limited places, advanced registration is essential
  • An optional lunch can be purchased during registration

An evening poster session and drinks reception will be held following the close of the meeting on Monday 19 November 2018. Whilst the posters are free to view for all registered participants, the corresponding optional drinks reception is ticketed. Drinks reception tickets can be purchased in advance during registration.

Enquiries: Contact the Scientific Programmes team.
