Figure 6. Locations of observed heat flow ( 1) for Sites 897, 898, and 900 along the composite seismic section, assembled from parts of the three seismic sections located in Figure 1. Conversion from two-way traveltime to depth assumes vw = 1.5 and vs = 2.0 km/s. Generalized interpretation of basement type follows Shipboard Scientific Party (1993); question marks indicate basement of uncertain origin. Predicted heat flow along profile (solid line) is calculated as described in the text.
