| bioclastic | sedimentary rock of once living material |
| clastic | a sedimentary rock of compacted and cemented rock fragments |
| contact metamorphism | when magma forces its way into overlying rock and changes it |

| igneous intrusion | magma cooling inside the earth |
| metamorphic | rock formed from heat and pressure on another rock |
| nonfoliated | metamorphism with an even crystal distribution |
