Rocks 3 - Metamorphic Rocks Rocks that form when a pre - existing rock ( protolith ) changes due to temperature or pressure, and/or as a result of squashing or shearing. Protolith – the pre - e Metamorphism. Metamorphic rocks: appear to have changed in their structure or chemical composition since their creation or formation.. Originally sedimentary or igneous. Altered by heat, pressure, or exposure to hot fluids in earth’s crust. HIGHER-GRADE REGIONAL METAMORPHICS. Gneiss and Eclogite. 2. High-Grade Regional Metamorphic Facies. Rocks in this laboratory represent high to very high grade regional metamorphic rock. Facies represented are the amphibiolite, granulite, and eclogite facies. LOWER-GRADE REGIONAL METAMORPHICS. Slate, Phyllite, . “Greenstone” and Schist. 2. Metamorphic Rock Definition. A sedimentary, igneous, or previously existing metamorphic rock which has undergone textural, structural, and/or mineralogical changes due to the action of one or more agents of metamorphism. LOWER-GRADE REGIONAL METAMORPHICS. Slate, Phyllite, . “Greenstone” and Schist. 2. Metamorphic Rock Definition. A sedimentary, igneous, or previously existing metamorphic rock which has undergone textural, structural, and/or mineralogical changes due to the action of one or more agents of metamorphism.

A sedimentary, igneous, or previously existing metamorphic rock which has undergone textural, structural, and/or mineralogical changes due to the action of one or more agents of metamorphism. Metamorphic Rocks. “Meta” means change (Greek). “Morph” means form (Greek). A rock that has been changed from its original form (parent rock) by heat, pressure, and fluid activity into a new form (daughter rock).. S6E5. .
