ODP Leg 174A: Mid-Atlantic Sea-Level Transect

Figure 4

FMS image across interval below pp4(s).


Preliminary correlation with core data suggest that conductive spots (dark) probably are pyrite-rich concretions. At these shallow depths, unconsolidated sands and silty-sands tend to be less resistive, whereas shales tend do be more compacted appearing brighter in the images. Bedding in this image is relatively faint, suggesting intense bioturbation.
