|---|---|---|
| Official designation | NWA 2501 | North West Africa 2501 |
| Meteorite class | Ordinary chondrite | Common group with distinct mineralogy |
| Fall or find | Find | Discovered on Earth's surface rather than witnessed fall |
| Mass available | Several documented fragments | Total mass varies by reported holdings |
| Main minerals | Olivine, pyroxene, metal | Used for classification and studies |
Origin and discovery context
The meteorite NWA 2501 was recovered in the Sahara region of North West Africa, a well-known area for meteorite finds. Local collectors locate fragments using systematic searching methods, after which scientific teams verify classification. Documentation includes recovery notes, photographs, and initial field classification to establish authenticity.
Physical characteristics and composition
Specimens of NWA 2501 typically show a mixture of chondrules and fine-grained matrix, which is typical for ordinary chondrites. Observed minerals include olivine, pyroxene, and nickel-iron metal, with varying degrees of weathering. Petrographic thin section analysis and bulk density measurements help quantify these physical traits for research and catalog records.
Scientific study and classification
Laboratory work on NWA 2501 includes chemical analysis through techniques such as X-ray fluorescence and electron microscopy. Teams assign a petrologic type and shock stage to communicate its thermal and alteration history. These classifications align with standard meteorite databases used by academic and institutional researchers.
Collection, preservation, and market considerations
Because fragments of NWA 2501 are widely distributed, responsible collectors document find spots and maintain provenance records. Proper storage in dry conditions minimizes oxidation and preserves scientific value for future study. The market price varies by mass, cut quality, and documentation completeness, influencing trade among dealers and institutions.
Key points and recommendations
- Confirm official designation and provenance through recognized meteorite databases.
- Document recovery details and physical properties to support scientific study.
- Use appropriate preservation methods to limit weathering and maintain specimen integrity.
- Consult peer-reviewed studies when evaluating classification and market information.
