Apr 10, 2025 · Aletai, discovery of new large mass. History: A new, 23 tonne mass of Aletai was found recently in a pasture of Aletai county (48°2’17"N, 88°23’3"E) in June, 2021. It was buried by soil and grass and covered with light-brown rust.

The Aletai meteorite is a rare type of iron meteorite from China, characterized by unique Widmanstätten patterns and high concentrations of gold and iridium

Jun 24, 2022 · The composition of Aletai irons is so unique that no other samples in the world meteorite collection are comparable. It seems too much of a coincidence if several meteorites with the same unique composition were from different fall events but are geographically on an array.

Jun 24, 2022 · Since 1898, five large, iron-rich meteorites have been found strewn across 430 kilometres near the China–Mongolia border. Only in recent years have scientists identified them all as fragments of...

Known for its unique "stone-skipping" trajectory, the Aletai meteorite presents a compelling subject for studying extraterrestrial materials. The research aims to characterize its bulk modulus, shear modulus, Young's modulus, and Poisson's ratio to evaluate its structural integrity and anisotropic behavior.

Jul 1, 2022 · Using numerical modelling, an international team of scientists have now found that the asteroid – known as Aletai, the Mandarin name for the area – probably entered the atmosphere at a low angle...

The Aletai iron meteorite forms an impact field more than 430 km long and consists mainly of iron with kamacite, taenite, plessite and schreibersite. The Aletai is officially classified as a IIIE iron meteorite. Read more.

Jul 20, 2022 · During their entry to Earth, meteoroids and asteroids can deposit energy, causing great concerns to astrophysicists. Recent discoveries of the massive Aletai irons in Northwest China constitute...
