Stishovite has the same chemical formula as silica quartz (SiO2) but it has much higher density. While SiO2 is abundant on Earth's crust, it is also a major component of basalt, a type of igneous rock that is rich in iron ...
A recent study published in Nature examines how mud cracks observed on Mars by NASA's Curiosity rover could provide insight into how life on the red planet could have formed in its ancient past.
