More Details About the O’Malley 001 Meteorite

O’Malley 001 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.
O’Malley 001’s official classification is H6. The “H6” classification refers to a high-iron, ordinary chondrite meteorite with distinct features like smaller chondrules and specific oxygen isotope ratios close to those found on Earth. This type 6 meteorite has undergone extensive metamorphism, leading to uniform mineral composition, larger secondary mineral sizes, and the fading of many chondrule outlines, yet without any melting.
The O’Malley 001 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.
