Mullion

(thing) by Kawika Thu Jul 19 2001 at 8:33:18
In geology, a mullion describes a linear, cylindrical structure comprised of elongated rods or columns 20 millimetres to 2 metres across and up, to 100 metres long.

The surface may be smooth or corrugated and define a lineation parallel to fold axes. Mullion structures are most common in strongly deformed metamorphic rocks, and may form by buckling of the surface between strong and weak rock beds.
