Roosevelt County 049 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.
Roosevelt County 049’s official classification is LL4. The classification “LL4” refers to an ordinary chondrite from the LL group that falls into petrologic type 4. Ordinary chondrites are a significant category of meteorites known for their unique chemical composition, high proportion of chondrules (tiny spherical grains), and specific isotopic characteristics. In this case, the meteorite is identified as type 4, indicating that it contains abundant chondrules and has undergone metamorphism, which altered the mineral composition and structure, but lacks primary igneous chondrule glass.
The Roosevelt County 049 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.
