Garnet and new rock type found in Mars meteorite

An international team of scientists has discovered a completely new type of rock and the mineral garnet in a fragment of a Martian meteorite. The findings provide fresh insights into the geological evolution of Mars, revealing previously unknown mineral compositions. Garnet, a gemstone popular since Roman times, had not been confirmed in Martian samples until now. The discovery challenges existing models of the Red Planet's crust formation and volcanic activity.
