Figure F49. Curated length of core recovered from the first three cores in all holes from Leg 209. Holes in basalt had notably low recovery compared to holes in peridotite and gabbroic rocks. Among holes drilled into peridotite and gabbroic rocks, Hole 1275C, drilled with resistivity-at-the-bit-while-coring (RAB-C) equipment, had the worst recovery (0.22 m curated length in 20.8 m of penetration), whereas Hole 1275D, ~3 m away from Hole 1275C but drilled with conventional rotary core barrel (RCB) equipment, had the best recovery (7.9 m curated length in 17.6 m of penetration).
