A 4.45 billion-year-old zircon grain, extracted from a Martian meteorite found in the Sahara in 2011, suggests Mars once had boiling hydrothermal systems similar to Earth’s volcanoes, according to a study published in Science Advances.
The discovery, led by researchers at the Perth-based Curtin University, also indicates that the planet may have been habitable at some point in its past and had the necessary conditions to support microbial life.
‘Black Beauty’ reveals Mars’ geologic diversity
The team studied meteorites from a space rock called NWA7034, or ‘Black Beauty’. Unlike most Martian meteorites, which are mainly igneous or mantle rocks, these provide unique insights into Mars’ geologic history.
“Micro- to nanoscale microscopy of a unique impact-shocked zircon from the regolith breccia meteorite NWA7034 reveals textural and chemical indicators of hydrothermal conditions on Mars during crystallization 4.45 billion years ago,” scientists noted in the abstract of the study.
Black Beauty is unique because it is a regolith sample from Mars’ surface, resembling soil, and contains hundreds of rock and mineral fragments from various sources across the planet, explains Aaron Cavosie, a planetary scientist from Curtin University’s Space Science and Technology Centre in Australia.
Around 20 meteorites found on Earth are believed to have been ejected from Mars during the impact that sent the original Black Beauty stone here. A tiny zircon grain within the meteorite, first studied in 2022, revealed insights into Mars’ early crust formation and preserved evidence of earlier meteorite impacts. These meteorites provide valuable clues to piece together Mars’ geological history, Cavosie observed.

The discovery, led by researchers at the Perth-based Curtin University, also indicates that the planet may have been habitable at some point in its past and had the necessary conditions to support microbial life. Researchers at Curtin University in Perth made the discovery. It also suggests that at one point, the planet was habitable and could have supported microbial life.

Scientists noted that "Micro to Nanoscale Microscopy" of an impact-shocked Zircon found in the regolith meteorite, NWA7034 revealed chemical and textural indicators of conditions at Mars' crystallization 4.45 billion years before.
Black Beauty is unique because it is a regolith sample from Mars' surface, resembling soil, and contains hundreds of rock and mineral fragments from various sources across the planet, explains Aaron Cavosie, a planetary scientist from Curtin University's Space Science and Technology Centre in Australia. Black Beauty, which is similar to soil on Mars, is unique in that it contains rock and mineral fragments originating from all over the planet. This is explained by Aaron Cavosie of Curtin University’s Space Science and Technology Centre.
Around 20 meteorites found on Earth are believed to have been ejected from Mars during the impact that sent the original Black Beauty stone here. It is believed that around 20 meteorites on Earth were thrown from Mars by the same impact which brought the Black Beauty Stone here. A tiny zircon grain within the meteorite, first studied in 2022, revealed insights into Mars' early crust formation and preserved evidence of earlier meteorite impacts. In 2022, a tiny zircon particle within the meteorite was studied for the first time. It revealed new insights about Mars' crustal formation, and evidence from earlier meteorite impact. These meteorites provide valuable clues to piece together Mars' geological history, Cavosie observed. Cavosie noted that these meteorites can be used to reconstruct the geological history of Mars.

Using nano-scale geochemistry, researchers found evidence of hot water on Mars 4.45 billion years ago. Researchers found hot water evidence on Mars 4.45 billion years old using nanoscale geochemistry. On Earth, similar systems played a crucial role in the development of life and early crust formation, providing the necessary conditions for early biochemical processes. Similar systems on Earth played an important role in life development and the early formation of crust, supplying the conditions necessary for biochemical processes.
Ancient zircon hints at early water presence. Ancient zircon suggests early water presence. Using nanoscale imaging and spectroscopy, the team identified element patterns in the zircon, including iron, sodium, yttrium, and aluminum. The team used nanoscale imaging to identify the element patterns of zircon. These included iron, sodium yttrium, and aluminum. These patterns showed that the elements were incorporated into the grain during its growth, forming layers similar to those of an onion. The patterns revealed that elements had been incorporated during the growth of the grain, creating layers that resembled those found in an onion.
"Hydrothermal systems were essential for the development of life on Earth and our findings suggest Mars also had water, a key ingredient for habitable environments, during the earliest history of crust formation," Cavosie said. Cavosie stated that "Hydrothermal Systems were Essential for the Development of Life on Earth. Our findings also suggest Mars had water during the early history of crust Formation, which is a Key Ingredient for Habitabile Environments." Zircons with similar patterns on Earth form in magmatic-hydrothermal systems, where heated water moves through rocks, carrying trace elements.
Cavosie also emphasized that the new study advances our understanding of early Mars by identifying telltale signs of water-rich fluids present when the zircon grain formed. It offers geochemical markers of water in the oldest known Martian crust. The study provides geochemical evidence of the presence of water within the oldest crust known on Mars.
