Subject field(s)
  • Soil Science
DEF

Soil derived from the serpentine mineral, and other ultramafic rocks [which is] characterized by unusual flora and often unforested or sparsely forested.

CONT

Some fungi tolerate easily the generally elevated metal contents of serpentine soils. Some of these fungal species are mycorrhizal.

OBS

Serpentine rock has a mottled, greenish-gray color with a waxy feel to it. These rocks form when the upper mantle of the earth's crust containing wet oceanic sediments is submerged under a land mass, which results in the chemical addition of water to heavy mantle rock.

French

Domaine(s)
  • Science du sol
CONT

Les sols de serpentine causent des modifications tant dans l'apparence que dans le fonctionnement des plantes. Ces modifications, conjuguées à l'isolement caractéristique des habitats de serpentine, favorisent la formation de nouvelles espèces.

CONT

Les plantes qui poussent sur des sols de serpentine ont à faire face à de faibles concentrations des principaux éléments minéraux et souvent à la toxicité de métaux lourds. De plus, les sols de serpentine ont généralement une faible capacité à retenir l'eau; les plantes qui poussent dessus sont donc habituellement adaptées au stress hydrique.

PHR

Sol composé de serpentine; sol riche, chargé en serpentine; sol formé sur serpentine.
