- The Diyodar Meteorite that crashed in Gujarat in 2022 is a rare aubrite, seen in India just once before in 1852.
About
- Aubrites are a type of meteorite that are coarse-grained igneous rocks formed in poor-oxygen conditions, and thus contain a variety of exotic minerals that are not found on Earth.
- For example, the mineral heideite was first described in the Basti meteorite.
- They are named after the Aubres meteorite, which fell in France in 1836.
- Around 90% of the Diyodar meteorite was composed of orthopyroxene. Pyroxenes are silicates consisting of single chains of silica tetrahedra. Orthopyroxenes are pyroxenes with a certain structure.
- Rocks with pyroxene have also been used to make crushed stone that is used in construction.
- When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
