U.S. Mars rover finds extremely rare ore or comes from volcanic eruption 3 billion years ago

A piece of the “extremely rare” mineral tridymite discovered unexpectedly at the floor of Mars’ Gale Crater may have been formed by a volcanic eruption more than 3 billion years ago.

Tridymite, a high-temperature and low-pressure form of quartz, puzzled scientists when it was discovered by NASA’s Curiosity rover in 2016 because the mineral is often associated with volcanoes on Earth, UPI reported. activity, and volcanic activity on Earth is already considered very rare.

The study, published online in Earth and Planetary Science Letters, is in line with a 2016 study that found a “silicon volcanism scenario” may be responsible for tridymite.

The new study further adds to the thermodynamic model explaining how tridymite was a “reasonable product” of the evolution of the same magmatic processes that produced other rocks in Gale Crater.
