Zircon is an excellent capsule to protect primary evidences of the ultrahigh-pressure (UHP) metamorphism, whereas mineralogic evidences of the UHP conditions were mostly obliterated in the matrix minerals of the rock due to the extensive retrograde overprinting related to exhumation. Zircons from the Kokchetav UHP-HP massif contain numerous inclusions of graphite, quartz, garnet, clinopyroxene, phengite, phlogopite, rutile, albite, K-feldspar, amphibole, zoisite, kyanite, calcite, dolomite, apatite and monazite, as well as diagnostic UHP minerals, microdiamond and coesite, which are identified by laser Raman spectroscopy. The diamond inclusions coexist with coesite and garnet, and appear also with low-pressure minerals, especially graphite in single zircon grains with zonal arrangements. Internal structure of zircon displays distinct zonal fabrics, which comprise inherited core, wide mantle and outer rim, each with distinctive inclusion micro-assemblages. These observations indicat-ed that zircon has been grown at several distinct stages including UHP mineral-bearing mantle, low-pressure mineral-bearing rim and inherited core containing low-pressure minerals. Sensitive high resolution ion micro-probe (SHRIMP) analyses of the zoned zircons resulted four discrete ages of the Kokchetav ultrahigh-pressure metamorphic rocks ; (1) Middle Proterozoic protolith age, (2) 537 ± 9 Ma for the UHP metamorphism, (3) 57 ± 8 Ma for the late-stage amphibolite facies overprint, and (4) 456-461 Ma for the post-orogenic thermal events. The zircon inclusion method presented here is a comprehensive technique to demon-strate the history of ultrahigh-pressure metamorphic rocks, and can be applied to understand P-T-time history of other UHP-HP metamorphic terranes.
