Question
1. In the same paleomagnetic study, the following stable directions of remanent magnetization, corrected for the dip of bedding in the limestone formation, were measured in five samples from the same site: Sample SR-04 SR-05 SR-07 SR-10 SR-12 329.7 336.6 326.2 40.6 24.7 46.0 40.9 44.9 322.7 (1) Calculate the direction cosines aN, EAv) of the north, east, and vertical components for each sample using the relationships ': cos l cos D A, = cos I sin D A, =sin 1 (2) Add up the values for each direction cosine. Let the sums be X, Y, and Z, where Calculate the vector sum of the directions, R, and the declination Dm and inclination Im ofExplanation / Answer
