PhD Title

Determination of stable osmium isotope fractionation within the Earths’ mantle.

Project Description

This research is part of the ‘Habitable Planet’ project led by Dr. Helen Williams. The PhD project will focus on the fractionation of stable Osmium (Os) isotopes within the Earth's mantle. The first stage of the project will involve the development of a new geochemical tool to determine stable Os isotope fractionation by multicollector mass spectrometry. Secondly, the method will be applied to multiple different mantle reservoirs to characterize the stable Os signature of the Earth's mantle. These data will be used to place constrains on secular variations in oxidation state and melting that have defined the evolution of Earth's mantle.
