Stylolite from the Helderberg Group, exposed on Corridor H

The stylolite is a pressure-solution surface, made especially apparent in this example because of the starkly different grain sizes and colors on either side of the dissolved-away rock:


This is a gorgeous sample to explore in macro GigaPan view. Enjoy:
