Abstract

Abstract

Retrograde eclogite was newly discovered in Jinshajiang suture zone in Ludian area of West Yunnan Province,which occurs as lenses in garnet muscovite quartz schist. The EPMA and LRS analyses reveal that there were residual omphacite inclusions in garnet and zircon. The muscovites developed in garnet and matrix are phengite(Si(p.f.u)=3.27-3.53),indicating that the rock has undergone a high pressure process of metamorphism. Garnets in this rock have preserved prograde metamorphic zonation. Petrographic and mineral chemical characteristics indicate that the retrograde eclogite has roughly undergone 4 generations of mineral assemblages including the progressive amphibolite facies mineral assemblage,the peak phase eclogite facies mineral assemblage,the early retrograde metamorphic mineral assemblage and the late strongly retrograde mineral assemblage. The typical paragenetic association of minerals of each stage is Grt+AmpI+Qtz,Grt+Omp+Rt+Qtz+Phe,Pl+Di+AmpⅡ+Ilm+Spn+Qtz,AmpⅢ+Pl+Czo+Ilm+Qtz,respectively. These new findings will provide important evidences and more restraints to the key scientific problems such as the complex P-T-t path style of metamorphic evolution and chronostratigraphic framework in Jinshajiang suture zone,the complex tectonic evolution history of Paleo-Tethys ocean of subduction,collision,orogenesis,and the collage mechanism of microcontinent and so on. It has important scientific significance.
