Tridymite Mineral Found By NASA On Mars
NASA’s Curiosity rover found an unexpected type of silica mineral on Mars called Tridymite.
Found in the Gale crater on Mars, and it could change what we know about how the planet formed. It’s called Tridymite, and it is a type of silica mineral.
“I always tell fellow planetary scientists to expect the unexpected on Mars,” Doug Ming, a co-author on the new paper, said in a statement. “The discovery of tridymite was completely unexpected. This discovery now begs the question of whether Mars experienced a much more violent and explosive volcanic history during the early evolution of the planet than previously thought.”

Why This Mineral Is So Surprising?
The presence of tridymite on Mars was a surprise because it’s associated with a specific type of volcanic activity called silicic volcanism. Scientists didn’t think was ever present on Mars.
NASA planetary scientist Richard Morris explained in a statement: “On Earth, tridymite is formed at high temperatures in an explosive process called silicic volcanism. Mount St. Helens, the active volcano in Washington State, and the Satsuma-Iwojima volcano in Japan are examples of such volcanoes. The combination of high silica content and extremely high temperatures in the volcanoes creates tridymite.”
The tridymite on Mars likely came from the erosion of silicic volcanic rocks, according to NASA. That means the planet may have once had violent volcanoes that spewed out silica-rich magma when it was first forming.
It’s possible that there’s a way for tridymite to form at lower temperatures than those associated with silicic volcanism, but scientists aren’t aware of it. The research will likely encourage other scientists to test if the mineral can form in other ways, according to NASA.
