Chondritic meteorites (chondrites) are some of the oldest rocks in our solar system, forming 4.5 billion years ago. Therefore, their primitive composition means that they offer a window into the ...

Chondrules have long been a puzzling feature of meteorites and, if they weren't observable in meteorites, scientists would likely never have predicted their existence, Minton said. "Chondrules are ...

Chondrules are such dominant features of these meteorites that they are called chondrites, and they account for 86 percent of meteorites that have been found on Earth. Their origin, however ...

Research suggests collisions of planetary embryos could be the origin of the material that formed asteroids. Chondrules, tiny bead-like grains of solidified melted rock found in meteorites, might ...

135-year-old meteorite mystery solved? Chondrules may have formed from high-pressure collisions in early solar system Date: July 8, 2013 Source: University of Chicago ...

Chondrules are silicate spherules that are found in abundance in the most primitive class of meteorites, the chondrites. Chondrules are believed to have formed by rapid cooling of silicate melt ...

These meteorites, which constitute more than 80 percent of those observed to fall from space, derive their name from the chondrules virtually all of them contain—tiny beads of melted material ...

The olivine found in chondrules presents a problem. If a shock wave formed the chondrules, then the olivine’s isotopic composition would be concentrically zoned, like tree rings. As the droplet cools, ...

Whether they are actually from Mercury remains unknown. However, both are achondrites, previously melted meteorites characterized by an absence of chondrules (mineral spheres embedded in the rock) and ...

Prior research had suggested that chondrules in some meteorites were probably born when rocks in space collided at speeds of more than 22,370 mph (36,000 km/h). However, it was uncertain how the ...

A study carried out by researchers from MIT and Purdue University seeks to challenge the established role of meteorites in planetary formation, arguing that rather than representing the kernel of ...
