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. The C chondrites represent only a small proportion (4.6%) [1] of meteorite falls.

a photo of the Ornans meteorite The Ornans meteorite is a carbonaceous chondrite and the type specimen of the CO group ( C arbonaceous O rnans group). Its fall was observed in France in 1868.

The Ornans (CO3.3) meteorite fell on 11 July 1868. A single stone of ~6 kg mass — which broke into two pieces — was recovered. Ornans is the prototype for the CO (Ornans-like) Carbonaceous Chondrites. Ornans was the first of the 6 CO meteorites …

Meteorite Name: Ornans. Type: CO3. Carbonaceous chondrite, Ornans group, type 3.3. Country: Doubs, France. Date of fall: 1868, July 11 (19h15). Tkw: 6Kg approx. Ornans : After detonations, a stone of about 6kg fell and broke into two pieces. Ornans is the classic standart of the "O" designation of Carbonaceous chondrites.

Ornans (below, left) has relatively small chondrules, while Vigarano (below, right) has notably larger chondrules. (Both images have been enlarged 30 times.) This meteorite is carbon-rich, or carbonaceous.

Rocks at Mouthier is a simple and powerful statement of one of Courbet's recurrent landscape themes, that of the high steep cliff structure of the region around Ornans.

Apr 1, 1977 · SIMILARITIES BETWEEN ORNANS TYPE CHONDRITES Prographie properties Chondrites of the Omans type are characterized by a distinctive texture with a high density of small (0.2-0.5 mm dia.) size-sorted inclusions, chondrules, …

From Ornans to the Nouailles Gorges to the sources of the Lison and Loue streams, stroll about the landscapes painted by Courbet by following these 8 discovery paths.

It is inferred that carbonaceous chondrite matrices are not pristine: they formed from a material reservoir that was already depleted in volatile and moderately volatile elements, which produces a highly nonmonotonic trace element pattern that requires a complementary depletion in chondrule compositions to achieve a monotonic bulk. ...

Gustave Courbet's "View at Ornans," painted in 1864 and currently residing in the Bowes Museum, offers a captivating glimpse into the French countryside. Measuring 1.295 meters wide by 0.863 meters tall, this landscape painting transports us …
