“…Stage 4 is defined by zircon U-b ages (~220 Ma) of Hujialin garnet-bearing clinopyroxenites as reported by Gao et al (2004) and the exsolution (garnet, clinopyroxene, magnetite, and ilmenite) of clinopyroxene during the exhumation (Zhang and Liou 2003;Li et al 2008). The peak P-T conditions (P ≥ 5.0 PGa; T ≥ 750°C) were estimated by Chen and Xu (2005) and Yang (2006) based on the Fe-Mg exchange of coexisting garnet and clinopyroxene.…”

“…However, coesite inclusions in zircons are also found in gneisses from the Sulu UHP terrane, indicating that the whole orogenic belt experienced UHP metamorphism [21]. Studies of garnet clinopyroxenite in the Hujialin area of the Sulu UHP orogenic belt were carried out in order to understand the petrogenesis and metamorphic evolution of these rocks [8,[22][23][24][25][26][27][28]. Hiramatsu and Hirajima [22] divided the metamorphic evolution of the Hujialin garnet clinopyroxenites into three stages, and calculated a peak metamorphic temperature of 740 • C with pressures above 2.5 GPa.…”

The Rizhao Hujialin area is located in the central Sulu ultrahigh-pressure orogenic belt, where garnet clinopyroxenite is exposed in the upper part of an ultramafic rock complex and serpentinized dunite is exposed in its lower part. Based on textural criteria, the garnet clinopyroxenites were divided into three types: Equigranular garnet, porphyroclastic garnet, and megacrystic garnet pyroxenites. The garnet clinopyroxenites have convex-upward chondrite-normalized rare earth element patterns, large positive Pb anomalies, and depletion of high-field-strength elements (e.g., Nb, Zr, and Ti), suggesting a mantle source protolith overprinted by fluid metasomatism. Petrographic, mineral chemistry, phase equilibrium modeling, and zircon U–Pb geochronology data show that the evolutionary stages of the Hujialin garnet clinopyroxenites were as follows: Stage I: formation of the magmatic protoliths; stage II: formation of megacrystic garnet pyroxenite accompanying subduction; stage III: formation of porphyroclastic or equigranular garnet clinopyroxenite with a mineral assemblage of garnet + clinopyroxene + ilmenite + humite accompanying initial exhumation at ~215.0 ± 5.7 Ma; stage IV = progressive cooling and decompression associated with the crystallization of water-bearing minerals such as clinochlore and pargasite at 206 Ma; and Stage V = late epidote amphibolite-facies retrograde metamorphism producing a mineral assemblage of garnet + clinopyroxene + amphibole + chlorite + epidote + ilmenite at ~180–174 Ma associated with fluid activity in shear–tensional fractures and/or pores. The P-T conditions of the peak metamorphism were estimated at 4.5 ± 0.5 GPa and 800 ± 50 °C. Retrograde metamorphism recorded conditions of 1.0 GPa and 710 ± 30 °C during the exhumation and cooling process. The mineral transformation from early high-Al clinopyroxene to garnet and to late diopside records the general metamorphic evolution during subduction and exhumation, respectively. One zircon U–Pb analysis presents the Palaeoproterozoic age of 1817 ± 40 Ma, which is coeval with widespread magmatic and metamorphic events in the North China Craton.
