Study Examines Whether Mars’ Missing Carbonate Rocks Lie Underground
A geochemical modeling study led by researchers at JAXA and the University of Tokyo examines the apparent absence of large stores of carbonate rocks on Mars. The researchers propose that carbonate deposits may be located deep underground, potentially bearing evidence of the planet’s watery past, according to Universe Today.
A geochemical modeling study led by researchers at JAXA and the University of Tokyo addresses what scientists describe as Mars’ “missing” stores of carbonate rocks.
The study examines whether carbonate deposits could exist deep underground rather than being largely visible at the Martian surface. If present, those rocks could preserve evidence related to Mars’ watery past.
THE QUESTIONS THIS EVENT LEAVES BEHIND
What observations could distinguish deep underground carbonate deposits from other explanations for their apparent absence?
How could future missions test whether carbonate rocks are buried beneath the Martian surface?
What assumptions does the geochemical model make about Mars’ past water and carbon cycles?
Could the proposed deposits be concentrated in regions that current missions have not examined?
What evidence would challenge the study’s interpretation?
