Sandstone Rock Mosaic
This is a view of a rock face in Carboniferous sandstones that I discovered some time ago. BEST VIEWED LARGE. The colours come from iron staining, but I'm not sure what actually caused the strange structures on the rock surface. It truly is a natural wonder. It became my 20th photo to reach Explore on March 16 2008 and my 4th shot to make 1000 views.
I later found that the structures were Liesegang Banding caused groundwater diagenesis of unconsolidated sandstones with the red colur coming from Fe rich groundwaters.
