Crystalline silica in meteorite brings scientists closer to understanding solar evolution

Scientists discovered silica mineral quartz in a primitive meteorite, becoming the first in the world to present direct evidence of silica condensation within the solar protoplanetary disk. They also found ultrarefractory scandium- and zirconium-bearing minerals in the meteorite, which implies that the minerals condensed from nebular gas over a wide temperature range.
