Figure F29. Examples of isothermal remanent magnetization (IRM) acquisition and demagnetization (backfield IRM) (see "Lowrie-Fuller Tests and Coercivity of Remanence Measurements" in "Rock Magnetism" in "Paleomagnetism and Rock Magnetism") used to calculate coercivity of remanence from Hole 1205A basalt: Samples (A) 197-1205A-4R-2, 16-18 cm, (B) 19R-4, 143-145 cm, (C) 24R-2, 141-143 cm, (D) 27R-4, 44-46 cm, (E) 29R-3, 114-116 cm, and (F) 35R-2, 36-38 cm. AF = alternating field, SD = single-domain, MD = multidomain.
