More Details About the Northwest Africa 7133 Meteorite
The Northwest Africa 7133 meteorite was discovered in 2010. It was recovered in Morocco (0.0, 0.0). It has a mass of 63.9 grams.
Northwest Africa 7133 is considered a “Valid” meteorite. “Valid” meteorites are typical meteorites with average weathering, while “relict” meteorites are those that have been extremely altered, either due to weathering over time or human intervention.
Northwest Africa 7133’s official classification is CO3.1. The classification “CO3.1” refers to a specific type of carbonaceous chondrite meteorite from the CO group, characterized by its close-to-solar magnesium and silicon ratios and oxygen isotopes that differ from those on Earth. These meteorites, specifically of the Ornans (CO) chemical group, contain small chondrules and inclusions, occupying about half of their volume, and show minimal signs of water-based alteration. They are also marked by a notable presence of chondrules, minimal water alteration, and a mixture of different minerals that haven’t fully chemically combined.
The Northwest Africa 7133 meteorite is a “Found” meteorite. Meteorites are classified as “falls” if they were observed falling and recovered, while “finds” are those discovered later, often weathered by longer exposure to Earth’s environment and without a record of being seen as they fell.
