Supporting dataset of the reaction zones and marbles in the Mogok metamorphic belt

The datasets include six tables. These tables include the information on the sample description, compositions of whole rocks and minerals, U-Th-Pb isotope data of baddeleyite and zircon, and mass-transfer calculation results for polycrystalline mineral reaction zones (PMRZs) in dolomite marbles from the Mogok metamorphic belt, Myanmar. The whole-rock compositions were determined by XRF and ICP-MS. The major elements of minerals were analyzed by EPMA, whereas the trace elements of minerals were analyzed by LA-ICP-MS. The U-Th-Pb isotope data were measured by SIMS.
