Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites. They include some of the most primitive known meteorites.
carbonaceous chondrite, a diverse class of chondrite s (one of the two divisions of stony meteorite s), important because of the insights they provide into the early history of the solar system. They comprise about 3 percent of all meteorite s collected after being seen to fall to Earth.
1 day ago · The Chicxulub impactor—known to schoolchildren as the asteroid that smacked into Earth 66 million years ago and killed off the dinosaurs—appears to be a carbonaceous chondrite, a rare and ancient type of meteorite that formed beyond the orbit of Jupiter. Other evidence had already pointed to this possibility, including a small fragment of ...
2 days ago · We just learned where the asteroid that ended dinosaurs came from Geological clues suggest that the space rock that created Chicxulub crater was a carbonaceous chondrite meteorite.
1 day ago · In this artist's impression, a large asteroid is seen impacting Earth. A new study has found that the asteroid that caused a mass extinction 66 million years ago was a carbonaceous chondrite that ...
Carbonaceous Chondrite refers to a type of meteorite that is classified based on its composition, elemental ratios, bulk composition, and oxygen isotopic ratios.
Carbonaceous chondrites are composed of several distinct components [2.6–2.8]: fine-grained darkmatrix, chondrules, high-temperature inclusions and opaque minerals. There is a variation in chemistry and relative abundance of these components among the different carbonaceous chondrite groups.
2 days ago · They analyzed ruthenium isotopes from the Chicxulub impact crater and concluded the impact was due to a carbonaceous-type asteroid, likely hailing from beyond Jupiter. As previously reported, the ...
2 days ago · The prime suspect in the extinction of the dinosaurs was no ordinary meteorite, researchers have revealed. Comparisons between the chemical record left behind by the strike 66 million years ago and known meteorite samples suggest that the Cretaceous meteorite was a carbonaceous chondrite.
2 days ago · One possibility is that these minerals were brought to Psyche by impacts with smaller carbonaceous chondrite asteroids that are known to contain substantial quantities of water.
