Geology Picture of the Day – Tessellated Pavement
Today’s geology picture of the day is a photograph by Dave Walsh (who is an absolutely incredible photographer, check it out!). The subject? Tessellated pavement on the Tasman Peninsula on Tasmania, Australia. Tessellated pavement is an interesting phenomenon that I’ve never heard of before. According to Wikipedia, it forms when rock subjected to various tectonic pressures (ie., fracturing during earthquakes one would assume) is then modified by sand and wave action.

From what I can find though, the information on this geological phenomenon is sort of lacking on the internet. Anyone have more information about these interesting structures?
(Apparently, I am not the only one to feature this as a picture of the day. I just discovered a website called “Earth Science Picture of the Day” and they feature the same tessellated pavement on January 23, 2007!)
