Supdataset.xls/x Table S1. Increasing metamorphic grade generally results in a coarsening of texture Metamorphic facies map of the study area. Bibliography • Bucher, K., & Grapes, R. (2011). 243) Click here for online mineral and rock ID charts. These conditions are less than those of blueschist. The boundaries between the facies are depicted as wide bands because they are gradational and approximate. Metamorphic Fabrics. Greenschist sample. Metamorphic facies. Chart of metamorphic facies showing mineral reactions and indicators for impure limestone, pelitic and mafic igneous protoliths (modified from Brownlow, 1979). Since they were muds and sandstones, there have been some metamorphic reactions producing chlorite, but they are still low grade, greenschist facies rocks. The fabric of a metamorphic rock also tells of its history. Foliated metamorphic rocks (Monroe; Table 8-2, pg. Petrogenesis of metamorphic rocks. Springer Science & Business Media. From Wikimedia. The common metamorphic facies. Some of the PDF files are animations -- they contain more than one page that can be shown in sequence to see changes as temperature or some other variable changes. Metamorphic lithology patterns (701–710) Igneous and vein-matter lithology patterns (711–33) 301-K 301-C 301-M 301-DO 302-K 302-C 304-C 305-K ... Pattern Chart [Pattern number below pattern box; lookup table symbol number in upper left-hand corner of color box] Title: of99-430_patternchart.eps They are usually named for their most common rock type or mineral. Table S2. The mineralogy of the a metamorphic rock is not the only line of evidence to determine its history. As you move Northwest into higher grade rocks (biotite, garnet zones), new minerals appear in a regular sequence and the texture of the rocks change, becoming more schist-like. All three represent common marine sedimentary facies which are probably metamorphosed by the weight of overlying debris . Results of the RSCM thermometry. Figure S3. Result of increasing heat and directed pressure. Greenschist is the name of a metamorphic facies, a set of typical minerals that form under specific conditions—in this case relatively cool temperatures at high pressures. The previous diagram depicts various Metamorphic Facies and their Temperature and Pressure Environments. Figure S1. Plots of Th vs. U and Th/U vs. REE contents for zircon from the host. Metamorphic facies The concept of metamorphic facies was first proposed by Eskola (1915) who later gave the following definition: A metamorphic facies is "a group of rocks characterised by a definite set of minerals which, under the conditions obtaining during their formation, were at … classification of metamorphic and other composite-genesis rocks, including hydrothermally altered, impact-metamorphic, mylonitic, and cataclastic rocks ... metamorphic facies and types.....46 12 appendix 4. glossary of metamorphic rock terms and parent-child ...

P-P = Prehnite-Pumpellyite facies. Metamorphic P-T Phase Diagrams. (a) Major and (b) trace element compositions for the granite in the composite veins, the host eclogite and the surrounding gneiss. A metamorphic FACIES includes all of the rocks and minerals that form in a given metamorphic environment under specific temperature and pressure conditions. But, at higher grades of metamorphism, in the upper amphibolite facies and the granulite facies, muscovite becomes unstable and is replaced by K-feldspar + quartz + an Al 2 SiO 5 mineral. Metamorphic petrologists studying contact metamorphism early in the 20th century introduced the idea of metamorphic facies (part of a rock or group of rocks that differs from the whole formation) to correlate metamorphic events.
