More Details About the Tennasilm Meteorite
The Tennasilm meteorite was discovered in 1872. It was recovered in Kiuma, Põlva maakond, , Estonia (58.03333, 26.95). It has a mass of 28500 grams.
Tennasilm 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.
Tennasilm’s official classification is L4. The classification “L4” refers to a type of ordinary chondrite from the L group. These meteorites are characterized as petrologic type 4, which means they contain numerous chondrules and have undergone metamorphism that altered the composition of olivine and the fine-grained matrix, but they lack primary igneous chondrule glass.
The Tennasilm 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.
