Figure 176-2. Possible N-S geologic cross sections of the Atlantis II Bank through Hole 735B, consistent with existing geological and geophysical data, gravity, and magnetics. Except at Hole 735B, fault locations and geometries are uncertain. The presence of a dike-gabbro transition as shown on the right of all the models is also hypothetical. A) Crustal stratigraphy around Hole 735B as suggested by Cannat (1993) and Swift and Stephen (1992), consistent with earlier inferences of Hess (1962). B) Crustal stratigraphy assuming Hole 735B is representative of the lower crust down to the mantle (Dick et al., 1991b). C) Crustal stratigraphy based on the layered intrusion model for ophiolites as proposed for Oman (After Pallister and Hopson, 1981; Smewing, 1981).
