chondrite

Many of the rocks contain small blue and red "inclusions" -- material trapped in the rock during its formation -- much like a type of rare, primordial meteorites found on Earth called carbonaceous chondrites.

Bose explains, "This means S-type asteroids and the parent bodies of ordinary chondrites are likely a critical source of water and several other elements for the terrestrial planets."

This part of the Takche Formation contains abundant traces of Chondrites and Zoophycos, and brachiopod and cephalopod fauna.

However, observations taken in 2014 with ESO's Very Large Telescope have again raised the question as to the origin of H chondrites (the H signifies "high" iron content, about 25-35% nickel-iron).

The meteorites studied were 'carbonaceous chondrites' - space rocks that originated from asteroids that are as old as our Solar System.

Effect of different chondrites on the parameter of rare-earth elements: and the theory of chondrite meteorites standard.

Searching a Swedish quarry, researchers discovered a new variety of meteorite that may have originated from the same cosmic collision that formed L chondrites, which make up around 40 percent of all known meteorites.

The information compiled on ordinary chondrites indicates that these meteorites originate from small asteroids which, with a diameter of less than a few hundred kilometres, collided, giving rise to these rocks millions of years ago.

About 15 years ago, "scientists began thinking that maybe Earth's water came from carbonaceous chondrites," Sarafian said.
