An extraordinary discovery has captured the attention of the international scientific community: researchers have identified a precious stone in a meteorite fragment that comes from Mars. This groundbreaking discovery was made by a global team led by Dr. Tanya Kizovski from Brock University in Canada, along with colleagues from prestigious institutions such as the Royal Ontario Museum and the University of Portsmouth.
Precious stone hidden in Martian meteorite
Published in the Geochemical Perspectives Letters journal, the study revealed the presence of garnet in the meteorite NWA 8171, a 4.4 billion-year-old piece preserved in Canada. This mineral, known for its ornamental value on Earth, has been identified for the first time in Martian material.
Dr. Kizovski commented that the discovery could offer new insights into Martian geological processes. The information acquired will help understand how Mars has evolved over time and provide new perspectives on its geological history.
For this study, advanced laser microanalysis technologies were used, revealing the presence of andradite, a variety of garnet rich in iron and calcium. Unlike traditional earthy gemstones, this andradite presents dark greenish and yellow tones.
Additionally, garnet on Earth acts as a record of extreme pressures and temperatures, suggesting that the original Martian crust experienced similar complex processes.
The finding was met with surprise due to the absence of plate tectonics on Mars. Experts propose two theories about the origin of the heat necessary to form the garnet: a meteorite impact or the rise of magma and chemical fluids from the planet’s interior.
To verify the Martian origin of the garnet, researchers plan to measure oxygen isotopes. If confirmed, an unknown Martian geological environment would be discovered. Alternatively, it could provide information about celestial bodies that impacted the solar system in the past.
The research is already sparking interest in the scientific community and promises to open new lines of investigation into Mars’ geological past.
