DEF

Renflement en forme de coquille se développant lorsqu'on brise certaines roches dures, sur la face d'éclatement du fragment détaché.

CONT

Le conchoïde, dit aussi «bulbe de percussion», prend naissance au point d'impact par un «cône de percussion», plus ou moins marqué. L'importance du conchoïde et le développement du cône paraissent en rapport avec la violence du choc et la dureté du percuteur employé.
