We are pleased to welcome Dr Romain Tartese from the University of Manchester, who will be delivering the School Seminar:-
Title: Origin of water in inner Solar System rocky bodies
Because they formed in close vicinity to the Sun, it is generally believed that inner Solar System rocky bodies accreted dry. Additionally, it is thought that any water and other volatile species should have been lost from bodies that were once fully melted, such as the Moon or the differentiated asteroid Vesta. And surely enough early investigation of samples brought back from the Moon in the 70’s failed to detect any significant quantities of indigenous lunar water. However, this “bone-dry Moon” paradigm has recently been overturned, thanks to continued analysis of returned lunar samples using modern analytical instrumentation. Analytical approaches combining measurements of volatile abundances in mineral phases together with their isotopic composition has proved to be vital to fingerprint processes and source(s) involved in giving rise to the lunar volatile inventory. These lunar-focussed studies quickly led to reinvestigation of the water inventory in meteorite samples from Mars and other differentiated rocky bodies, which we will review during the seminar. While all these recent studies have undoubtedly measured indigenous water in samples from inner Solar System rocky bodies, they have also highlighted some challenges that need to be overcome in order to comprehensively characterise the origin and processing of volatiles in the inner Solar System.
All staff and students welcome.
