Minerals and Rocks
1 reportResearch on Minerals and Rocks examines an Earth process, material, landscape, water system, or hazard through field and geophysical evidence. Current understanding relies on petrographic analysis, igneous rocks, and primary observations, with uncertainty tracked across measurement, classification, and reconstruction.
Igneous rocks and direct observations are treated as separate lines of evidence. Their combined record addresses how minerals are identified and what rock textures reveal, showing how sparse measurements or incomplete records limit certainty.

Perseverance Finds Three Water Episodes in Ancient Mars Rocks
Perseverance has analyzed igneous rocks in Mars' Jezero Crater that record at least three separate interactions with water, including a later episode involving heated underground fluids.
