Across
- 3. The darkest coloured part of a Migmatite
- 7. A metamorphic agent which promotes chemical reactions and exponentially increases the rates of solid-state atomic diffusion
- 8. A fabric term used to describe a metamorphic rock with segregated banding of light and dark coloured minerals. i.e. this rock sample has __________ banding
- 10. Wavy or flat PLANAR features in a metamorphic rock
- 11. A metamorphic rock of mixed appearance which has partially melted during metamorphism. The melted fraction has then resolidified in situ
- 12. Changes in the size, shape, orientation and distribution of pre-existing minerals
- 14. The original, unmetamorphosed rock from which a given metamorphic rock is formed
- 15. The lightest coloured part of a Migmatite
- 17. The differential, or partial, melting of rocks, especially in the formation of metamorphic rocks
- 18. Metamorphism involves a change to the rock in terms of (beginning with ‘D’)
Down
- 1. A metamorphic agent which promotes changes to denser mineral structures and raises a rock’s melting point
- 2. Metamorphism involves a change to the rock in terms of (beginning with ‘V’)
- 4. Term used to describe the change of minerals or geologic texture in pre-existing rocks, without the original rock melting into liquid magma –
- 5. A type of metamorphism in which the mineralogy and texture of rocks are changed over a wide area by deep burial and heating associated with the large-scale forces of plate tectonics
- 6. Formation of new crystals (due to mineral reactions)
- 9. Metamorphism involves a change to the rock in terms of (beginning with ‘S’)
- 13. The sub parallel to parallel alignment of elongate LINEAR fabric elements in a rock body
- 16. A type of metamorphism in which the mineralogy and texture of a body of rock are changed by exposure to the pressure and extreme temperature associated with a body of intruding magma
- 18. A type of metamorphism produced by mechanical forces. Associated with zones of high to moderate strain such as fault zones
