Figure F333. Relationship between velocity (average of x-, y-, and z-velocity measurements) with (A) porosity and (B) bulk density in Expedition 312 samples is weak. For Hole 1256D, velocity decreases as (C) porosity increases and as (D) bulk density decreases. A shift of 0.42 km/s has been applied to Expedition 312 measurements to account for intercalibration problems (Fig. F330). Primary lithology: circles = sheet flows, squares = massive flows, crosses = breccias, triangles = dikes, diamonds = gabbros. Red = Leg 206, green = Expedition 309, blue = Expedition 312.
