- Bioclastic sedimentary rocks are formed from the remains of living organisms.
- Carbonate rocks are a type of bioclastic rock with high amounts of calcite and/or dolomite.
Metamorphic Rocks
- Metamorphic grade measures the intensity of change in a rock due to heat, pressure, or chemical conditions.
- Foliation is the parallel layering of minerals in a rock, often a result of metamorphic processes.
