The Pyroxene Group

The density of this mineral is 2800-3700 kg/m3

The Pyroxene Group is a group of Mg, Fe, Ca, Na, Al, and Ti silicates, including specific minerals such as augite, wollastonite, diopside, enstatite, and hypersthene. The density is high. These minerals are common in meteorites as well as in basic planetary igneous rocks. They constitute roughly 10% of Earth's crustal minerals. They have a single chain tetrahedral structure which makes them moderately resistant to weathering.
