Summary

[edit]
Description
Deutsch: Kryolith, Aegirin
Größe: ~ 2 x 2½ x 2 cm.
Fundort: Steinbruch Poudrette, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Kanada
Beschreibung: Kryolith? Welcher Kryolith? Nun – die winzigen Kryolith-Oktaeder bedecken alles, einschließlich einiger Ägirine. (Die auf anderen Foto gezeigte Gruppe ist die „Brücke“ unten rechts in diesem Foto.) Aber es ist nicht wirklich ein Kryolith-Pseudomorph. Die weißen Prismen selbst sind nach einem unbekannten Vorläufer wahrscheinlich Mikroklin und/oder Analcim und/oder Natrolith. Die Oberfläche (unter dem Kryolith) ist tatsächlich von eingewachsenen Analcim-Kristallen bedeckt.
English: Cryolite, Aegirine
Size: ~ 2 x 2½ x 2 cm.
Locality: Poudrette quarry (De-Mix quarry; Demix quarry; Uni-Mix quarry; Carrière Mont Saint-Hilaire; MSH), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada
Description: Cryolite? What cryolite? Well – the tiny cryolite octahedra coat everything including some of the aegirine. (The group shown in the parent photo is the “bridge” at lower right in this photo.) But it’s not really a cryolite pseudomorph. The white prisms themselves are probably microcline and/or nalcime and/or natrolite after an unknown precursor. The surface (under the cryolite) is actually covered by intergrown analcime xls.
