Published by Oxford University Press AB - The kinetics of the irreversible reaction Ca(OH) 2 + MgCO 3 → CaCO 3 + Mg(OH) 2 were investigated at high pressures and temperatures relevant to metamorphic petrology, using both in situ synchrotron X-ray diffraction and post-mortem analysis of reaction rim growth on recovered samples. Reaction kinetics are found to strongly depend on water content; comparable bulk-reaction kinetics are obtained under water-saturated (excess water, c. 10 wt LB - PUB:(DE-HGF)16 UR - <Go to ISI:>//WOS:000383734100006 DO - DOI:10.1093/petrology/egw044 UR - https://bib-pubdb1.desy.de/record/311029 ER -
