A new constraint on the central Andean rotation pattern from paleomagnetic studies in the southern Subandes of Bolivia

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Paleomagnetic Rotations in the Northeastern Caribbean Region Reveal Major Intraplate Deformation Since the Eocene

“…We then follow an approach similar to that of Calvagno et al. (2020) to compute the relative rotation and its confidence limits. We compute the difference in declination between each re‐sampled direction and the reference paleomagnetic direction and subsequently average those differences to obtain a single estimate of the relative rotation ∆ R i (for the i th iteration).…”

“…Next, a reference paleomagnetic direction is computed from a paleomagnetic pole that is calculated as the mean of a random draw (with replacement) of the same number of VGPs as the number of directions obtained for the studied block. We then follow an approach similar to that of Calvagno et al (2020) to compute the relative rotation and its confidence limits. We compute the difference in declination between each re-sampled direction and the reference paleomagnetic direction and subsequently average those differences to obtain a single estimate of the relative rotation ∆Ri (for the i-th iteration).…”
