Summary[edit]
| Description |
Deutsch: Der Gesteinsbrocken stammt vom Laacher-See Gebiet (Nähe Manderscheid, Eifel). Er hat eine Masse von gerundet 520 Gramm. Die auf dem Photo sichtbare Höhenausdehnung ist etwa 12 cm, die Breite knapp 9 cm. Der Brocken lag mehrere Jahre im Freien. Die Kanten lassen sich mit der Hand leicht abbrechen. Beim Heranzoomen erkennt man leicht grünliche Bereiche. Diese lassen sich auch unter Licht mit einer Geologen-Lupe erkennen: es ist dünner Bewuchs (Moos, Flechten?). Sehr dunkle Bereiche können Minerale sein (Pyroxene, Augit?). Das Bild entstand in der Mathe-AC Lernwerkstatt in Aachen. |
