Answers
Answer:
metamorphism is one type of rocks. This rock is changed by the intense heat and pressure.In the very hot and pressured condition deep inside the earth"s crust.
Answer:
Metamorphism is defined as follows: The mineralogical and structural adjustment of solid rocks to physical and chemical conditions that have been imposed at depths below the near surface zones of weathering and diagenesis and which differ from conditions under which the rocks in question originated.
Three types of metamorphism exist: contact, dynamic, and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism.
Mica-schist, chlorite-schist and talc-schist are a few examples from this group. ... Garnet-schists, cordierite-schists and staurolite-schists are common examples. Origin: Slates and schists are generally the product of dynamothermal metamorphism of argillaceous sedimentary rocks like clays and shales.
