| 英文摘要 | In his discussion, Ji ascribes our results to other workers and, using quotation marks, alleges statements that do not exist in our papers. We interpret some textures in the Yangkou eclogite breccia to be the result of rapid crystallization of local melts, but do not regard the entire breccia or the matrix to be pseudotachylyte. These, combined with the formation of the eclogite breccia from the coronitic eclogite wallrock and the preservation of intergranular coesite, imply transient (coseismic) high-pressure metamorphism. It is clearly indicated that the coesite-bearing eclogites followed a decompression and cooling path from about 3.3 GPa and 700 degrees C to about 0.3-0.6 GPa and < 375-400 degrees C, at which intergranular coesite and high-pressure microlites quenched. But Ji takes the pressure change to be from 3.3 to 1.2 GPa. The intercrystalline pressure vessel effect advocated by Ji for a compressed material should not be significant in subsequent decompression, particularly when considering the exhumation of intergranular coesite surrounded by fine omphacite grains in a deeply subducted slab. |
