Research Abstract |
Multi-solidphase inclusions (MSIs) composed of clinozoisite (Czo) + ky + qz have been found within garnets and in the matrix of metapelits from the Makbal complex in Kyrgyz. The reconstructed compositions of MSIs are consistent with lawsonite (Lws). Petrological study showed that Lws was stable at UHP stage (ca. 3 GPa and 550C) and decomposed to the MSIs during isothermal decompression around 1.6 GPa and 550C. Trace element characteristics of Czo grains in the MSIs show a flat REE chondrite-normalized pattern, identical to the typical REE pattern of Lws. Thus, the REE content of Czo in the MSIs included in garnet was likely inherited from the former Lws as the decomposition reaction took place isolated from the matrix. Lws decomposition and Czo-forming reactions accompany fluid release during the isothermal decompression stage, implying that the fluids can be generated not only during subduction, but also during exhumation of UHP rocks in cold subduction settings.
