What historical Martian process is indicated by the presence of calcium sulfate veins in the Cheyava Falls rock?
Answer
Movement of liquid water through rock cracks
The veins of calcium sulfate found in the rock indicate that liquid water once moved through fractures in the geological material, depositing minerals along the way. This evidence of fluid movement suggests the area had a history of hydration that could have potentially supported chemical or biological activity.
