A RAS Specialist Discussion Meeting, organsed by *John Bridges (Leicester)
Susanne Schwenzer (Open University)*Contact: Forty years after the Viking mission landings on Mars in 1976, our view of Mars as an inactive, entirely basaltic planet has changed radically. Recent results from Mars Science Laboratory show localised silica enrichments and evolved igneous rocks within the clasts and fluvio-lacustrine sediments of Gale Crater. Many new martian meteorites are being identified and include evidence for magmatic differentiation. The martian meteorites also record hydrothermal alteration of the martian crust. An objective of this meeting is to produce a review paper about our current state of knowledge on Mars magmatism and differentiation of the crust.
