- 2. /iron meteorites which contain more than 16% Nickel. They do not display a Widmanstatten Pattern.
- 4. /a mineral group of silicate minerals commonly containing calcium, sodium, potassium and aluminium.
- 8. /A mixing of different petrologic stages of same composition
- 10. /in the last couple of seconds of luminous flight, the molten surface of a meteor solidifies to form a thin, usually black 'fusion crust'.
- 13. /these meteorites have formed from material that was liquefied or partially liquefied from the extreme pressure and heat generated by a large meteorite or asteroid impact in space.
- 14. /is a meteor that has survived entry through the atmosphere and reached the Earths surface.
Down
- 1. /is an iron-nickel mineral low in nickel content. (Up to about 7.5%)
- 3. /a body of material enclosed by a different material
- 5. /Stony or Iron meteorites usually composed of olivine crystals set in a matrix of metallic iron.
- 6. /an Achondrite made of fragments of other types, usually Eucrite, Diogenite, Mesosiderite and chondrite. Howardites are broken meteoritic soils from the surface of an asteroid.
- 7. /is an iron-nickel mineral high in nickel content.
- 9. /meteorites usually composed relatively evenly of iron/nickel and stony material.
- 11. /formed from the collision of a large natural body from space when it impacts a large body's (eg. planets, moons, asteroids) surface at high velocity.
- 12. /are volcanic rocks primarily composed of the minerals olivine, pyroxene and feldspar.
