Figure 7. Depth variations in relative abundance of smectite, illite, and chlorite + kaolinite (<2-µm-size fraction) for hemipelagic mud samples from the Hydrothermal Transition Transect (Sites 1023, 1024, and 1025), the Buried Basement Transect (Sites 1028, 1029, 1030, and 1031), and the Rough Basement Transect (Sites 1026 and 1027). See Figure 3 for descriptions of lithostratigraphic units. Dashed vertical lines correspond to mean values for each mineral group.
