QUE SIGNIFIE GLAUCONITE EN ANGLAIS
Glauconite
Le glauconite, également connu sous le nom de «sable vert», est un minéral de phyllosilicate de fer potassium de couleur verte caractéristique avec une très faible résistance aux intempéries et très friable. Il cristallise avec une géométrie monoclinique. Son nom est dérivé des glaucos grecs signifiant «bleu», se référant à la couleur bleu-vert commune du minéral; Son éclat et sa couleur bleu-vert se rapportant vraisemblablement à la surface de la mer. Sa couleur varie du vert olive, du vert noir au vert bleuâtre, et jaunâtre sur les surfaces exposées en raison de l'oxydation. Dans l'échelle de Mohs, il a une dureté de 2. La gamme de gravité spécifique relative est de 2,4 à 2,95. Il se trouve normalement dans des granulés fragiles arrondis de vert foncé et avec une dimension de grain de sable. On peut confondre avec du chlorite ou avec un minéral argileux.
