Geology of the Arabian Plate - International Conference in Oman
In early January 2012 Mike Styles attended the International Conference in Muscat on the Geology of the Arabian Plate and the Oman mountains that included a session on CO2 sequestration. Much of the emphasis was on in situ sequestration by mineralisation led by the keynote speaker Peter Keleman from Columbia University, USA. This involves pumping seawater down an injection borehole to a depth of around 2 km to promote fracturing and carbonation of the host peridotite and recovery through a collector borehole for further recycling. There are serious efforts to obtain funds for an experimental borehole to investigate the viability of the technique as little is known about the nature of ultramafic rocks at this depth. The contribution from BGS covering a description of extensively carbonated ophiolite-derived conglomerates from the UAE demonstrated a natural analogue of the process envisaged but at much lower temperatures and pressures. There was particular interest in the extent of carbonation of the rocks and the volume involved that have captured the equivalent of at least 100yrs of current UK CO2 emissions.
