Figure 36. Behavior of declination (a, c) and inclination (b, d) of the field in the process of cooling of the Bushveld intrusion. The second variant of the record. a) Result of combining data of D for the first set of data (one Curie point is 580oC), after subtraction of the mean value from each sample. b) Result of combining data of I for the first set. c) Result of combining data of D for the second set (two Curie points, 556oC and 580oC), after subtraction of the mean value from each sample. d) Result of combining data of I for the second set. Points - initial data, line - result of averaging (H = 0.25) and transition to a uniform time step (Dt = 0.5).
