More Details About the Nobleborough Meteorite
The Nobleborough meteorite was discovered in 1823. It was recovered in Nobleboro, Lincoln County, Maine, United States (44.08333, -69.48333). It has a mass of 2300 grams.
Nobleborough 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.
Nobleborough’s official classification is Eucrite-pmict. The “Eucrite-pmict” classification indicates an achondrite from the eucrite group, specifically characterized as a polymict breccia, which means it consists of various rock fragments fused together. These meteorites are a key part of the most abundant basaltic achondrite group, distinguished by their Fe-rich pyroxene and Na-poor plagioclase, and are closely related to diogenites and howardites within the HED meteorite family, potentially deriving from asteroid 4 Vesta.
The Nobleborough meteorite is a “fall” 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.
