Figure 2-16

ANGUS 124, 35º08'N, 35º33'W. Field of view 5 x 7 meters. Probable fault scarp in carbonate mud with debris flow at base. Debris flow shows extensive signs of reworking by bottom grazers. 115

Figure 2-17

ANGUS 122, 35º08'N, 35º07'W. Field of view 4 x 6 meters. Fault scarp in poorly consolidated carbonate showing extensive evidence of gullying and degradation. Lighter streaks are exhumed (?) sediment flowing downhill. 116

Figure 2-18

ANGUS 126, 35º02.6'N, 35º22.5'W. Field of view 5 x 7 meters. Lithified carbonate encrusted with manganese that is interpreted to show substantial erosion of original sediment probably by winnowing. 117

Figure 2-19

ANGUS 126, 35º02.2'N, 35º22.5'W. Field of view (4-6) x (4-10) meters. Steep wall of lithified breccia. Minor amounts of sessile faunas.

Figure 2-21

ANGUS 124, 35º12'N, 35º33.6'W. Field of view 5 x 7 meters. Low amplitude possible wave ripples in carbonate mud. 121

Figure 2-22

ANGUS 126, 35º10'N, 35º20'W. Field of view 5 x 7 meters. Longditudinal triangular ripples in unconsolidated pteropod shells. These form parallel to the direction of the current flow. 122

Figure 2-23

ANGUS 126, 35º04.6'N, 35º26.2'W. Field of view 5 x (5-8) meters. Parallel grooves (abyssal furrows) in carbonate ooze. These are believed to form parallel to the direction of the prevailing current. 123

Figure 2-24

ANGUS 126, 35º02.2'N, 35º22.5'W. Field of view 4 x (3-8) meters. Steep breccia wall with luxuriant growth of sessile faunas. 124

Figure 2-25

ANGUS 122, 35º08'N, 35º31.7'W. Field of view 5 x 7 meters. Shoestring rills forming in unconsolidated sediments at the head of a scarp.
