Representation of paleomagnetic data in virtual globes: A case study from the Pyrenees

• We propose 3D models for the visualization of paleomagnetic data in virtual globes.
• A macro-enabled spreadsheet (P2K) generates KML files from paleomagnetic datasets.
• This tool allows accurate representation of declination, inclination and α95.

Virtual globes allow geo-referencing and visualization of diverse geologic datasets. A vertical axis paleomagnetic rotation study in the Southern Pyrenees, Spain, is used to illustrate the potential of virtual globes for representing paleomagnetic data. A macro-enabled workbook that we call P2K, allows KML files to be generated from conventional paleomagnetic datasets. Cones and arch models are used to represent the paleomagnetic vector, and the rotation with regard to the local reference direction, respectively. This visualization provides simultaneous representation of local magnetic declination, inclination and precise confidence cones, shown in their geographic position from diverse perspectives and scales.
