PPT-Lecture Ten Metamorphism of

pelitic rocks What is the Metapelites Metapelites are metamorphic rocks which derived from contact or regional metamorphism of shale or mudstones clay rich sediments Metapelites. Rock Environments. Metamorphic Environments. What Is Metamorphism?. Metamorphism. . Changes rock via temperatures and/or pressures unlike those in which it initially formed. All metamorphic rocks have a .

Develop the discretised 2D heat equation by varying the model’s thermal properties and implementing progressive metamorphism. LOWER-GRADE REGIONAL METAMORPHICS.

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.
