While on my blueschist quest, I noticed this boudin train exposed in the trail.
I’m not sure what exactly is being boudinaged here – only that it is lighter in color than the schist that surrounds it, as well as finer grained and less foliated (more massive). A tabular mass of fault gouge perhaps?
That’s nothin’… you should try the chocolate boudinage!
