Figure F2. Depth of penetration of drill holes into in situ basement clustered by broad spreading rate subdivisions where slow < 40 mm/yr < intermediate < 80 mm/yr < fast. Black lines = DSDP drill holes, blue lines = ODP drill holes, red lines = Holes 1256C and 1256D drilled into basement during Leg 206.
