Summary
| Description |
English: Sunrise, “Tessellated Pavement”, Eaglehawk Neck, Tasman Peninsula, Tasmania, Australia. The „Tesselated Pavement“ is the result of an orthogonal joint pattern in the rock. On the picture it shows the so called “pan formation”, where the rock in the immediate vicinity of the joints is more resistant to erosion than the rock that is more distant to the joints, This is due to alterations of the rock along the joints by hydrothermal (or similar) solutions when the rock was still buried deeply below the surface millions of years ago. When no alterations or alterations that lower the erosional resistivity have taken place in the geological past, the rock along the joints will erode faster than the rock that is more distant to the joints. In that case the so called “loaf formation” of “Tessellated Pavement” will form.
Français : Lever de soleil sur un pavement en mosaïque naturel à Eaglehawk Neck, en Tasmanie (Australie).
Deutsch: Sonnenaufgang bei Ebbe am Eaglehawk Neck, Tasman-Halbinsel, Tasmanien, Australien. Das Gestein zeigt eine natürliche Parkettierung (Tesselation), die auf ein rechtwinkliges Klüftungsmuster im Gestein zurückgeht. Auf dem Foto äußert sie sich in Gestalt sogenannter „Beckenstrukturen“, bei der das Gestein in der unmittelbaren Umgebung der Klüfte erosionsresistenter ist, als das Gestein in größerer Entfernung zu den Klüften. Dies ist wiederum das Ergebnis einer Gesteinsumwandlung entlang der Klüfte durch hydrothermale (oder ähnliche) Lösungen, zu einer Zeit als das Gestein sich noch tief unterhalb der Erdoberfläche befand, vor Millionen von Jahren. Falls keine Umwandlungen stattgefunden haben oder Umwandlungen, die zu einer Herabsetzung der Erosionsresistenz führten, erodiert das Gestein entlang der Klüfte schneller als das Gestein in größerer Entfernung zu den Klüften und es bilden sich „Brotlaibstrukturen“ (im Deutschen auch als Wollsackverwitterung bezeichnet). |
