Dimmitt is an ordinary chondrite type H3.7. It was discovered in the United States in Texas in 1942.
To date, only 75 meteorites of this type have been discovered, so it is a rare meteorite.
Dimmitt is a black regolith breccia with H3, H5 and LL clasts and a dark matrix that together account for ~95% of the meteorite volume.

NWA 13881 is a CV3 type meteorite with very large chondrules.
CV3 chondrites are characterized by the presence of large chondrules, abundant pre-solar isotopes and white inclusions called CAI’s.
CAI’s are mineral inclusions rich in calcium and aluminum, formed 4,567 to 4,571 million years ago they are the oldest materials in the Solar System.
