  • Metamorphic Rock Types: Pictures and Descriptions

     · Metamorphic rocks are an important topic in geology.These are the rocks that form by the effects of heat, pressure, and shear upon igneous and sedimentary rocks. Some form during mountain-building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism.

  • sand and aggregates, crushing, maximum yield

  • sand and aggregates, crushing, maximum yield

    Such extremely crushed metamorphic rocks are described as mylonites. Contact Metamorphism of granites involves, most commonly, simple recrystallisation of the constituent minerals. In regional metamorphism, however, when the heat factor is actively associated with pressure and chemically active fluids, granites and other related igneous rocks show very considerable and …
