Final Activity Report Summary - TIMPANI (Timescales of Igneous and Metamorphic Processes - Accessing new Information)
Project TIMPANI has been concerned with the development of a computer model for analysing compositional profiles within mineral grains. The model allows the timescales of high-temperature processes to be constrained within a variety of geological materials, including volcanic, metamorphic and meteorite samples. This has great use for examining the timescales of processes occurring before volcanic eruptions; rates of processes in metamorphic settings or the timescales of assembly and destruction of meteorite parent bodies.

Project objective
To investigate the timescales of plutonism, metamorphism and textural ripening through the integration of crystal size distributions (CSD), micro-beam analysis (micro XRF, microprobe, SEM), intra- and extra-crystalline diffusion based upon that data, geothermobarometry, and general petrology/ textural development as well as computer modelling of re-crystallisation regimes in contact metamorphic settings. The project will look at samples from the aureole of the Mt. Capanne pluton, Elba, which encompasses a wide variety of metamorphic protoliths (pelites, carbonates, flysch and igneous rocks), allowing the effects of the same temperature-time path on different lithology to be investigated and quantified. Spatially well-constrained samples will be taken from any lithology during fieldwork and the patterns of metamorphic and textural development of each suite will be related to a modelled temperature field constrained by geothermometric data. It is hoped that a toolbox of techniques based upon intra-crystall ine diffusion will be developed for accessing temperature-time information during the course of this work, based upon simpler techniques the applicant has devised for igneous settings. Progress permitting; the techniques developed during this investigatio n may be then extended to the more complicated case of regional metamorphic settings.
