Figure F20. Rock magnetic data for discrete samples, Hole 1117A. A. Plot of AMS parameters P_j vs. T, calculated according to Jelinek (1981). B. Plot of the acquisition of isothermal remanent magnetization (IRM) vs. applied field (T = Tesla). C. Plot of the normalized decay of anhysteretic remanent magnetization (ARM) during AF demagnetization (mT = milliTesla; J = remanent intensity; and Jo = initial intensity).
