Figure F25. Representative vector endpoint diagrams (Zijderveld, 1967) of magnetization directions for discrete basaltic samples through (A, B) stepwise AF demagnetization and (C) stepwise thermal demagnetization. Both demagnetization techniques revealed well-defined remanence components. Sample in B shows negative inclination. Open squares and solid circles represent the projection of the magnetization vector endpoints onto the vertical and horizontal planes, respectively. NRM = natural remanent magnetization.
