High-precision isotopic constraints on the timescale of orogenic metamorphic and magmatic processes

PROJECT DETAILS ONLY - NO DATA. This proposal aims at obtaining high-precision isotopic analyses on igneous and metamorphic phases at a length scale and precision necessary to resolve the timescales on which metamorphic and magmatic processes occur. The research requires the high-precision analysis of small amounts of Sr. and Nd by mass spectrometry. Given modern mass spectrometric techniques, the principal remaining controlling factor on the data obtained is the Faraday data collection system. Funding is sought herein to install a new and improved collection system on an existing mass spectrometer in the Department of Earth Sciences at the Open University.
