description Ornans Overview
Ornans is a carbonaceous chondrite meteorite that fell near Ornans in the Doubs department of France in 1868. It is the type specimen for the CO, or Ornans-type, group of carbonaceous chondrites, whose members contain abundant small chondrules and primitive rocky material. Its classification makes it significant to researchers studying early Solar System solids, parent-body alteration, and relationships among carbonaceous meteorites.
insights Ranking position
Ornans ranks #36 of 213 in the Meteorite ranking, behind Fukang, ahead of Wabar.
help Ornans FAQ
When and where did the Ornans meteorite fall?
The meteorite fell near Ornans in the Doubs department of eastern France in 1868. Because the fall was observed and material was recovered, scientists can study it without uncertainty about a terrestrial source location.
Why is the Ornans meteorite scientifically important?
Ornans is the type specimen for the CO group of carbonaceous chondrites. The letters "CO" derive from Ornans, linking the entire meteorite class to this French fall.
What does a CO carbonaceous chondrite contain?
CO meteorites are primitive stony meteorites characterized by small chondrules and refractory inclusions within a fine-grained matrix. These components preserve evidence from the early solar system before planets fully formed.
Is the Ornans meteorite made mostly of iron?
No. Ornans is a carbonaceous chondrite, a type of stony meteorite, rather than an iron meteorite like the body associated with the Wabar craters.
