The oldest solids formed in the solar system are inclusions enriched in calcium and this metal inchondrite meteorites.
The oldest solids formed in the solar system are inclusions enriched in calcium and this metal inchondrite meteorites. It's not magnesium, but one isotope of it has a 0.73-million-year half-life and isused as a clock for early solar system events. With clay and iron, this metal is leached from the Ehorizon. Except for quartz, all tectosilicates contain this element. Corundum is a crystalline form ofthis element's oxide. Along with silicon, oxygen, calcium, and alkalis, this metal is found in a mineralthat comes in orthoclase and plagioclase types and is the (*) most common rock-forming mineral in thecrust; that mineral is feldspar. Cryolite is used to extract this metal in the HallÂ–Heroult process frombauxite. For 10 points, name this most abundant metal in the Earth's crust.
