The morphology and chemistry of the majorite-pyrope garnet and the size of the magnesiowüstite crystals indicate a longer duration at high pressure and temperature than predicted by impact scenarios. This pressure-temperature regime is constrained by the olivine-ringwoodite and orthopyroxene-majorite phase transformations, fusion of the meteorite constituents, and crystallization of majorite-pyrope solid solution plus magnesiowüstite from that melt under high pressure.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699995738062336","@type":"Researcher","foaf:name":[{"@value":"Ming Chen"}],"jpcoar:affiliationName":[{"@value":"M.
