Figure 2.

Cartoon summarizing the development of joint sets (Pastor-Galán et al., 2011) and the acquisition of multiple magnetizations (Weil et al., 2001, 2010) in the Cantabrian arc during formation of the Cantabrian Orocline. (A) Joints and paleomagnetic vectors interpreted to develop contemporaneously with formation of a nearly linear Variscan orogen in pre-Moscovian and Moscovian times. (B) Arc during the uppermost Kasimovian and Gzhelian times when between 30% and 50% of the arc’s present-day curvature was attained, deposition of the Stephanian B–C basins occurred, and development of fold-axis subparallel and subperpendicular Stephanian joint sets were formed. (C) Present-day geometry of the Cantabrian Orocline and the orientation of the Early Permian paleomagnetic vectors showing no rotation. (D) Proposed timeline for successive magnetizations recorded in the Cantabrian Orocline and their relationships to the main phases of oroclinal formation and formation of sedimentary basins.
