New Model Explains Mars' Missing Carbonate Rocks

Geochemical modeling by JAXA and the University of Tokyo suggests massive carbonate deposits exist deep within the Martian crust, hidden beneath the surface.

The top 3

  1. JAXA and UTokyo Research Partnership: The study was led by researchers from the Japan Aerospace Exploration Agency (JAXA) and the University of Tokyo, focusing on planetary geochemical cycles.
  2. The Missing Carbon Problem Explained: Atmospheric models previously failed to account for enough CO2 to explain Mars' ancient liquid water, identifying a 'missing' carbonate signature.
  3. Subsurface Sequestration Mechanism: Simulation results indicate that hydrothermal processes sequestered volcanic CO2 into deep-seated carbonate minerals, keeping it out of detectable surface layers.
