Yet another triangle zone

by David Tanner, Leibniz Institute for Applied Geophysics (LIAG), Hannover, Germany

Two opposing thrusts (25 cm high hammer for scale; offsets less than 20 cm) that form a triangle zone. From an outcrop of radiolarite interbedded with thin claystones near Lautenthal in the Harz Mountains of Germany.
