FORMATION OF METAMORPHIC ROCKS
Metamorphic rocks record how temperature
and pressure affected an area when it was forming. The rocks
provide clues to their transformation into a metamorphic rocks.
Metamorphic rocks are best identified when looking at the rock as you
see them in nature. You can clearly see the deformation and
features that are characteristic of an entire area.
Metamorphic rocks were once sedimentary, igneous,
or another metamorphic rock. These rocks are physically deformed and
chemically changed due to different temperatures and pressures. The
elements in the minerals can actually "move" to form new
minerals. The rock does not melt, or else it would be considered an
igneous rock. A rock looks different after it has been metamorphosed.
The rocks texture and overall appearance changes also. It now has a
