NWA 14016 HED BRECCIA

N14016

Complete Slice

This meteorite slice is characterized as a Eucrite-melt breccia. It features a complex texture, with a grey-black melt matrix encasing rounded eucrite clasts. These clasts are observed at various stages of melting, illustrating the dynamic processes involved in their formation.

One of the most notable aspects of this specimen is the presence of gas vesicles—unusual for meteorites—which can reach sizes up to 2 centimeters. The combination of melt matrix and vesicles gives the slice a striking, abstract appearance, reminiscent of an artistic study of solar system processes.

Despite its rarity and the unusual features it displays, the price point for this eucrite-melt breccia meteorite is considered low, making it an attractive option for collectors interested in unique and scientifically significant specimens.

The specimen is provided with a cusioned riker mount case.

  • Mauritania
Group:
  • Stone
Type:
  • Achondrite, HED
Class:
  • Eucrite
Total known weight: 29.4 kg

June 2020, two identical stones were purchased in Mauritania. One 19.2 kg and 10.2 kg. Classification made by Irving (University of Washington, Seattle, WA) and Carpenter (Washington University, St. Louis, Mo) 2022 MB 110 as a Eucrite-melt Breccia

Petrology: Monomict breccia composed of angular eucrite clasts with intergranular texture in a fairly sparse melt rock matrix (dark gray in thin section) containing entrained crystalline debris. Minerals are exsolved pigeonite, calcic plagioclase, silica polymorph, chromite (some grains compositionally zoned) ilmenite, troilite and Ni-free Fe metal. Some thin dark shock veinlets crosscut clasts, and secondary calcite is present as veins and also infilling cavities in the matrix. High shocked and low weathering grade.
