Bjergmassiv
Aïrbjergene i Niger er et eksempel på et massiv
Ansigterne på Mars er et massiv uden for Jorden
Et massiv er i geologi betegnelsen for en stabil bjergmasse, der ikke internt påvirkes ret meget af pladetektonik, men primært flyttes som en samlet masse. Massiver er mindre enheder end de plader, der bevæger sig ved pladetektonik.
På Jorden findes en række massiver, heriblandt:
- Aïrbjergene, Niger
- Annapurna, Nepal
- Centralmassivet, Frankrig
- Jurabjergene, Frankrig
- Logan-massivet, Canada
- Mont Blanc-massivet, Frankrig/Italien/Schweiz
- Vinson-massivet, Antarktis
- Vogeserne, Frankrig
Massiver kendes ud over fra Jorden også fra andre himmellegemer; på Mars er de såkaldte "Ansigter" et eksempel på et massiv.

Martian face viking.jpg
The Face on Mars was one of the most striking and remarkable images taken during the Viking missions to the red planet. Unmistakeably resembling a human face, the image caused many to hypothesize that it was the work of an extraterrestrial civilization. Later images revealed that it was a mundane feature rendered face-like by the angle of the Sun.
