Introduction
Last week we learned about the processes that act to break down rocks at
earth’s surface, and we also explored the lithification processes that turn
weathered rock fragments into new sedimentary rocks. However, this is not
the end of the story for geological materials at earth’s surface. We know that
earth’s tectonic plates are constantly rearranging the crust, and this can
cause large pressure and temperature gradients at tectonic boundaries.
Rocks in these regions can be subjected to high pressures and/or
temperatures that can rearrange the minerals’ crystal structure. These
changes (collectively called metamorphism) can affect the rock’s
mineralogy (chemical composition) and/or its texture or appearance. Rocks
that have undergone these changes are called metamorphic rocks.

Figure 6-1. Metamorphic Temperature and Pressure Conditions. Note that
diagenesis refers to changes that happen at near-surface conditions during the
sedimentary lithification process, and it is not considered a metamorphic process.
Additionally, at very high temperatures and pressures, rock will melt into magma and
undergo other igneous processes.
Metamorphism can alter any rock that is subjected to temperatures and
pressures that are much greater than surface conditions but are not high
enough for the rock to re-melt into a magma. The pressure and temperature
conditions that the rock (called a protolith or parent rock) experiences
determine how much change occurs to the rock. Rocks that are altered at
lower pressure and temperature conditions are called low-grade
metamorphic rocks; rocks that are altered at very high pressure and
temperature conditions are called high-grade metamorphic rocks. The
grade of metamorphism is directly related to how much change can be
observed in the structure of the rock.
Figure 6-2. Metamorphic grade increases as pressure and temperature
increase. This figure shows that shale (a sedimentary protolith) changes form and
takes on very different physical properties depending on the pressure and
temperature conditions that it encounters during metamorphism.
