More Details About the Lake Bonney Meteorite
The Lake Bonney meteorite was discovered in 1961. It was recovered in 772X+2X Canunda SA, Australia (-37.75, 140.3). It has a mass of 2750 grams.
Lake Bonney 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.
Lake Bonney’s official classification is L6. The “L6” classification signifies a low-iron ordinary chondrite from the L group, characterized by a specific range of oxygen isotopes and moderate-sized chondrules. This type 6 meteorite has undergone extensive metamorphism, leading to uniform mineral composition, transformation of pyroxene types, and larger secondary minerals, while maintaining the original chondrule shapes without melting.
The Lake Bonney 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.
