The Curiosity rover’s campaign in the Gale crater (Mars) provides a large set of close-up images of sedimentary outcrops displaying a variety of diagenetic features such as light-toned veins shown in the model. We reconstruct the vein network of a sample area, recorded between sols 1536 and 1545, and estimated the stress field. Assessment of the spatial distribution of light-toned veins shows that the basin materials, after burial and consolidation, experienced a sub-vertical compression and lateral extension coupled with fluid overpressure and cracking due to infilling processes.
Photogrammetric mosaic from MASTCAM images. Full dataset will be publicly available soon.
