1. A rock formed by deposition and lithification of sediments
3. Sedimentary rock, particle size is mostly <1/256 mm, feels smooth to the touch,
formed by compaction and dessication, represents low –energy environment of
4. Metamorphic, foliated, megascopic, may contain bits of the mineral garnet, parent rock
can be granite or shale.
7. Igneous, glassy, non-vesicular, can be different colors.
10. Metamorphic, non-foliated, dominant mineral is calcite.
11. Igneous, glassy, vesicular, does not float.
12. Sedimentary, formed through chemical precipitation, contains banded/layered calcite,
often composes stalagmites or stalactites.
13. A rock that recrystallizes by changes in temperature and/or pressure without
complete melting.
14. Metamorphic, foliated, microscopic, has sheen.
2. A rock formed by complete melting.
4. Clastic sedimentary rock; particle size is 1/16–2 mm, grains visible without the aid of a
microscope; feels rough, moderate-to-higher-energy environments of deposition.
5. Sedimentary, contains rounded clasts >2 mm, formed by cementation, high energy
environments of deposition.
6. Metamorphic, foliated, megascopic, zebra striped, parent rock is granite or shale.
8. Igneous, crystalline, porphyritic, commonly contains hornblende and plagioclase.
9. Igneous, crystalline, phaneritic, commonly contains quartz, pink orthoclase, and mica.
