  6. 17. A rupture in the crust of a planetary-mass object.
  7. 18. Mixture of molten or semi-molten rock.
  8. 22. A sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments.
  9. 25. The transformation of a pre-existing rock.
  10. 26. A Igneous rock that is granular and phaneritic in texture.
  11. 27. Formed through the cooling and solidification of magma or lava.
  12. 28. A metamorphic rock formed by ductile deformation of a protolith with a large shear strain.
  13. 29. A dark green mineral consisting of hydrated magnesium silicate, sometimes spotted like a snake's skin
  14. 33. Study of rocks
  15. 34. A naturally occurring material that is broken down by processes of weathering and erosion.
  16. 35. A fine-grained grey, green or bluish-purple metamorphic rock easily split into smooth, flat plates.
  17. 36. A metamorphic rock formed by the contact between mudstone, shale, or other clay rich, rock.
  18. 37. A dark igneous rock composed of calcium plagioclase, pyroxene, and minor olivine, but no quartz.
  19. 38. A Igneous rock typically composed largely of plagioclase with pyroxene and olivine.
Down
  1. 1. A metamorphic rock form characterized by banding caused by segregation of different types of rock.
  2. 2. A solid mineral material forming part of the Earth's surface.
  3. 3. A hard non-foliated metamorphic rock which was originally pure quartz sandstone
  4. 4. A type of foliated metamorphic rock created from slate that is further metamorphosed.
  5. 6. A metamorphic rock typically containing muscovite, biotite, chlorite, and quartz
  6. 7. The result of magma reaching the surface either as lava or fragmental ejecta.
  7. 8. A metamorphic rock that has a hard compact variety of coal and has a sub metallic luster, also has the highest carbon content.
