Nov 09, 2022Temperatures of 302-392 degrees Fahrenheit (150-200 degrees Celsius) are needed to change a rock into a metamorphic rock. Because of this, metamorphic rocks transformed by heat must be transformed deep within the surface of the earth. Specifically, the rocks are located where magma is either created or expelled from the center of the

Metamorphic Rock Textures. There are two basic types of metamorphic rock texture, foliated and non-foliated (see Figures 8-5 and 8-6). Foliated In layered or foliated metamorphic rocks, the platy minerals are aligned in a parallel orientation. The size of the minerals (very fine-grained, fine grained, coarse grained) is related to the intensity of

The most obvious features of metamorphic rocks are certain planar features that are often termed s-surfaces. The simplest planar features may be primary bedding (akin to the layering in sedimentary rocks). As the rock crystallizes or recrystallizes under directed pressure, new crystals may grow in some preferred direction, sometimes subparallel to the primary bedding
