Figure F79. Grain size variations of the groundmass crystals in the basal crust of the lava pond in Hole 1256C. A. Clinopyroxene. B. Magnetite. Solid circles = average maximum length, open circles = average maximum width, squares = diameter of a circle with an equivalent area to the crystal, crosses = maximum width/length ratio. C. Plagioclase.
