Figure F2. Lithologic summary of the interval of sampling in Hole 1213B. Interestingly, magnetic susceptibility is higher in the interiors of the three massive lava flows in Hole 1213B and gradually lower toward the top and base of each flow, where petrography analyses indicates smaller crystal sizes for titanomagnetite, the sole oxide mineral observed in these basaltic flows and thus likely the carrier of the magnetic signal.
