A light-colored hypabyssal igneous rock characterized by a fine-grained allotriomorphic-granular (i.e. aplitic) texture.

French

Domaine(s)
  • Pétrographie
DEF

Roche granitique à grains très fins (0,5 mm environ) en général de couleur claire, à quartz, oligoclase et microcline, avec muscovite et tourmaline rares.

CONT

[...] les granites [...] sont le plus souvent, d'après la nature de leurs plagioclases, des monzogranites et des granodiorites. [...] Si les éléments deviennent très fins, on a une aplite, roche qui se présente en filons dans le granite. Au contraire, des éléments de grande taille constituent une pegmatite.

CONT

Parmi les aplites, signalons l'Elvan, aplite à mica blanc liée aux filons stannifères.

CONT

Aplite rubanée.

OBS

On [...] rencontre souvent [l'aplite] dans les filons traversant des massifs granitiques.

Spanish

Granito en filones, de color claro, formado por granos muy pequeños (no perceptibles a simple vista), constituido por cuarzo y feldespatos alcalinos, con pequeñas proporciones de mica, muscovita y biotita.
