Figure F55. A. RM = (RM₀ - RM₅)/(RM₂₀ - RM₅₀) (log scale) vs. compressional wave velocity (V_P). B. RM (log scale) vs. inclination of soft component. RM = ratio of the vector difference between steps of progressive AF demagnetization, RM₀ - RM₅ = the vector difference between the untreated NRM and NRM after demagnetization at 5 mT, RM₂₀ - RM₅₀ = the difference between the NRM after 20-mT treatment and NRM after 50-mT treatment. Open circles = lava flow samples, solid circles = volcaniclastic samples.
