| 1. metamorphism
| a. metamorphic rocks that don’t have foliation, lineation and directional texture
|
| 2. contact metamorphism
| b. scaly foliation composed of large-grained minerals that you can see without magnifying them
|
| 3. aureole
| c. locking minerals that don’t align themselves in any particular direction or fashion.
|
| 4. regional metamorphism
| d. when granite withstands the high heat and pressure of metamorphism
|
| 5. foliation
| e. hot magma comes into contact with the country rock and the heat from the intruding magma causes the country rock to metamorphose
|
| 6. slaty cleavage
| f. minerals in an igneous rock, or the particles in a sedimentary rock in certain circumstances (under extreme conditions of pressure or temperature) change and recrystallize
|
| 7. schistosity
| g. the part of the country rock that metamorphoses as a result of contact with the magma
|
| 8. gneissosity
| h. the heat and pressure is great enough to cause rocks to change their mineral composition and crystalline textures
|
| 9. hornfels
| i. a texture caused by the alignment of minerals into parallel bands
|
| 10. metamorphic rocks
| j. the coarsest foliation characterized by alternating bands of light and dark minerals.
|
| 11. gneiss
| k. high pressures and temperatures affect huge areas of the Earth’s crust, metamorphosing huge regions of rocks
|
| 12. hornfelsic (granular) metamorphic rocks
| l. it can easily be split along cleavage planes and the planes often have bumpy parallel ridges
