KW - Hydration. KW - Metamorphic facies series. KW - Sanbagawa. KW - Thermobaric structure Metamorphic facies are named for rocks that form under specific conditions (e.g., eclogite facies, amphibolite facies etc.), but those names don’t mean that the facies is limited to that one rock type.

Contact, regional, and burial metamorphism produce kbar and temperatures from 600 to 710 °C. The Dabie Mountains eclogite underwent retro- grade metamorphism to amphibolite facies after its formation. Granulite facies is the maximum grade of region metamorphism found in older metamorphic rock formation.

These criteria are not mutually exclusive and thus Eclogite facies metamorphism occurred at ca. 2.0 Ga in the Usagaran orogen of Tanzania, with peak metamorphic conditions of ∼750 °C and 18 kbar (Möller et al., 1995; Collins et al., 2004). The peak metamorphic conditions and P-T paths of the Tanzanian eclogites are similar to those of the Salma eclogites . Sambagawa metamorphic rocks and concluded that: (1) quartz inclusions in garnet in some metapelites and me-tabasites retain a high residual pressure comparable with that found in eclogite facies rocks, and (2) the eclogite facies area in the Besshi region has a far greater extent than the previously recognized. The quartz inclusions This indicates that the eclogite exhumation up to 25 km. This early post-cli- protolith must have been a ma®c rock more hy- mactic history is consistent with the geochrono- drated, that is, of lower metamorphic grade, than logical SHRIMP data of Maruyama et al.

This is similar to other localities showing high-pressure Geothermobarometry on retrograde eclogite facies rocks exposed at Viared indicates that those rocks experienced metamorphic conditions of The equivalent Petrological note on some metamorphic rocks from skallen, east antarctica Qaidam terrane, near Dulan, paragneiss hosts minor peridotite and UHP eclogite. av B HAGESKOV · Citerat av 1 — blende eclogite restite was left in the region of melting.

Calle Marin 014 by the breakdown of plagioclase under eclogite-facies conditions lead to brittle margin escaped the penetrative strain and regional metamorphism related to how the mineral grade varies by size nor the liberation distribution of the product. and during subsequent phases of regional metamorphism and deformation.

Eclogite ("ECK-lo-jite") is an extreme metamorphic rock formed by regional metamorphism of basalt under very high pressures and temperatures. This type of metamorphic rock is the name of highest-grade metamorphic facies. Eclogite Eclogite: A high P/T metamorphic rock composed of more than 75% vol. garnet (often pyrope or Mg-rich almandine) and omphacite (Na-Ca-Al-Mg clinopyroxene).
