Dr Timothy Holland FRS
Petrologist, Department of Earth Sciences, University of Cambridge
Timothy Holland has made fundamental and enduring contributions to petrology. He was the first to show that surface rocks had been buried to over 70 km. He has worked to construct a self-consistent thermodynamic database which describes equilibria among the multi-component mineral phases important in rocks and with full propagation of errors. This work, among the most highly cited in the geosciences, now underpins most petrological research. Recent advances include the calculation of mineral assemblages and compositions as a function of composition, pressure and temperature and the thermodynamic modelling of silicate melts, critical to tectonic interpretations of deeply buried rocks.
