Figure F12. Photomicrographs of veins formed of aggregates of small calcite grains. A, B. Lentil-shaped aggregates (thins section TS 64–71, open nicols). Rectangle = location of B. C, D. Aggregates of calcite grains drawing the cataclastic foliation (thin section TS 71–78, open nicols). Rectangle = location of D. White arrow = movement along microfaults, black arrow = direction of core top.
