Grapevine Mesa is a rare CBa Carbonaceous Chondrite found on 6 February 2021 on Grapevine Mesa, east of Meadview in Mohave County, Arizona, USA. It was discovered by Todd Parker and Robert Ward while metal detecting, with 550.3 g recovered from a small area. As a CBa meteorite, it belongs to the Bencubbin-like Carbonaceous Chondrites, an uncommon group known for high metal content and unusual early solar system formation history.

Specimens of Grapevine Mesa are notably metal-rich, with silicate fragments set among abundant iron-nickel metal. Published descriptions note rounded to angular silicate fragments hosted by metal grains, with the metal-rich texture closely resembling Bencubbin. Natural pieces may show rusty exteriors with patches of fusion crust, while prepared fragments can reveal the striking contrast between bright metal and darker silicate material.

For collectors, Grapevine Mesa offers a scarce opportunity to acquire an officially recognised Arizona Carbonaceous Chondrite with a rare CBa classification. Its limited recovered mass, American provenance, and Bencubbin-like structure make it especially appealing for specialist Chondrite and USA meteorite collections. Each specimen represents an unusual metal-rich pathway of early solar system material formation.

Important information for all items

How the scales and gridlines work.

Each small square is 1x1mm, and each bold-lined square is 10x10mm, or 1cm² (1 square centimetre).

Imperial measurements.

1 inch is is easy to figure because it is about 25 small squares, which is 2½ bold squares.

The piece shown in the photo on the left (a Gebel Kamil Iron) is about 70mm from left to right, which is about 2¾ inches, and around 60mm (about 2⅓ inches) from top to bottom.
