Two hundred years in the future, in a fully colonized solar system, police detective Josephus Miller (Thomas Jane), who was born in the asteroid belt, is given the assignment to find a missing young woman; Julie Mao (Florence Faivre).
Perlite is made from a mined volcanic glass of the same name. As a raw material it contains water, trapped by the rapid cooling of lava. The moisture vaporizes explosively when heat is applied.
Olivine, of which peridot is a type, is a common mineral in mafic and ultramafic rocks, and it is often found in lavas and in peridotite xenoliths of the mantle, which lavas carry to the surface; but gem quality peridot only occurs in a fraction of these settings.Peridots can be also found in meteorites.Olivine in general is a very abundant mineral, but gem quality peridot is rather rare. This is due to the mineral's chemical instability on the Earth's surface.Olivine is usually found as small grains, and tends to exist in a heavily weathered state, unsuitable for decorative use.livine is a silicate mineral with the formula of (Mg, Fe) 2 SiO 4. As peridot is the magnesium-rich variety (forsterite) the formula approaches Mg 2 SiO 4.
