In a recent discovery, a collaborative team of scientists from Allahabad University and the University of Bern, Switzerland, revealed that the Dhala crater resulted from the collision of an ...

It is now believed that the ureilite meteorite, likely measuring 1 km in diameter, impacted on the granitoid rocks of the Bundelkhand craton at an extraordinary speed (>15 km/sec), resulting into ...

We suggest here that the diaphite described by Nemeth and Garvie in Canyon Diablo (4, 5) may be the precursor to lonsdaleite formation in ureilite meteorites. Intense shock is needed to form diaphite, ...

This does not happen with lonsdaleite in ureilite meteorites from the mantle of the dwarf planet. The hexagonal structure makes it potentially harder than regular diamonds, which are cubic.

Notably, lonsdaleite doesn't form on Earth and has, so far, only been discovered in a certain type of meteorite called ureilite meteorites. Despite it not having an Earth origin, researchers have ...

The lead scientist on the research team, Prof. Andy Tomkins, said the rare diamond's mysteries drove him to continue researching ureilite meteorites in his lab. “This is exactly the sort of ...
