Journal of Structural Geology - Photograph of the Month by Benoit Taisne

13 Jan 2014

The Journal of Structural Geology's Photograph of the Month was taken by Assistant Professor Benoit Taisne. The spectacular columnar jointed basalts on the picture are located on the border between Slovakia and Hungary, in Somosko. Columnar jointing like the one visible on this outcrop is generally associated with the solidification of lava during its cooling. This lava was in the neck of an ancient volcano that was active around 4 million years ago.
