A study published in Nature Astronomy on June 26, 2026 has rewritten what we know about Mars' geological past. Titled "Seismic evidence for a melt-depleted lower crust and transcrustal magmatism on Mars", the research reveals that the Red Planet once hosted enormous, Earth-like magmatic systems deep beneath its surface — despite lacking the plate tectonics long thought necessary for such geological complexity .
What researchers found 24 km below the surface
Using seismic data from NASA's InSight mission, University of Oxford researchers analyzed a boundary located about 24 km beneath the Martian surface. By comparing hundreds of possible rock compositions with seismic data through thermodynamic modeling, they identified a clear compositional split .

A study published June 26, 2026 in Nature Astronomy reveals that Mars once hosted enormous, Earth like magmatic systems deep beneath its surface, despite lacking plate tectonics.
What are the key points to validate first?
A study published June 26, 2026 in Nature Astronomy reveals that Mars once hosted enormous, Earth like magmatic systems deep beneath its surface, despite lacking plate tectonics. The findings suggest that complex crust and geological recycling—key for habitability—can occur on planets without plate tectonics, expanding the range of worlds that might support life.
Above 24 km: Rocks were mafic (higher silica content).
Below 24 km: Rocks were ultramafic (rich in iron and magnesium, low in silica) — consistent with a melt-depleted lower crust.
This boundary is the key signature of a process previously thought unique to Earth.
The process: transcrustal magmatism
The team concluded that molten rock pooled deep underground and gradually separated into different materials. Dense crystals settled at the base of the crust while lighter, more evolved melts rose upward. This process is known as transcrustal magmatism.
On Earth, transcrustal magmatism occurs beneath volcanic arcs and is linked to continent formation. Scientists had assumed that such complex crustal processing required the constant recycling of rock driven by plate tectonics .
Challenging a long-held assumption
Mars is a "stagnant lid" planet with no moving tectonic plates. For decades, planetary scientists assumed that plate tectonics was essential for producing complex, evolved crust and geological recycling. The new discovery shows that Mars built complex crust through intense internal recycling alone, without any plate tectonics .
Co-author Prof. Jon Wade of the University of Oxford explained the significance: if Mars could develop this kind of complex crust without plate tectonics, "then maybe the conditions needed for habitability can emerge on more planets than we realized, including those previously dismissed based on size or their apparent lack of tectonic activity" .
Implications for planetary habitability
The study carries profound implications for where and how scientists search for life beyond Earth. Geological recycling helps regulate climate and sustain the cycling of water and volatiles — ingredients essential for life as we know it .
The evidence suggests that such magmatic systems may extend for hundreds or thousands of kilometers across Mars' northern hemisphere, indicating interconnected magma systems rather than isolated volcanoes .
Built on InSight's legacy
This finding is the latest in a string of revelations from NASA's InSight mission, which operated on Mars from 2018 to 2022. Despite the lander's retirement, the data it collected continues to yield fundamental insights. InSight's seismometer, the Seismic Experiment for Interior Structure (SEIS), recorded over 1,300 seismic events during its mission . Previous studies using InSight data have identified a liquid core, revealed a solid inner core , and uncovered evidence of subsurface water .
The June 2026 Nature Astronomy study adds a transformative piece to that puzzle, showing that even a geologically "quiet" planet like Mars can generate the kind of magma-driven complexity once considered a hallmark of Earth-like worlds.
