Figure F4. Diagram of room-temperature hysteresis loop for representative basalt samples that exhibit SD, PSD, and MD behavior. (A) PSD Sample 183-1136A-16R-1, 80-82 cm, (B) SD Sample 183-1140A-26R-2, 15-17 cm, and (C) MD Sample 183-1142A-9R-3, 33-35 cm. Horizontal axis is applied field up to 1 T. Vertical axis is mass-specific magnetization (corrected for slope).
