Carbonaceous Chondrite (C2-ung; S1)
~10 kg recovered in small fragments (fresh & weathered)

An unusually bright meteoritic fireball preceded the fall of an unusually primitive Carbonaceous Chondrite. Tagish Lake exploded over the skies of Yukon Territory, British Columbia, Northwest Territories, and Alaska on January 18, 2000. Most of the fragments found were from Tagish Lake, and most were actually found within British Columbia. Calculations using seismic and satellite data suggest that a preatmospheric porous meteoroid with a ~ 5 m diameter and roughly 100 ton mass created the spectacular pre-dawn display which produced the relative meager surving material we now label the Tagish Lake meteorite. Carbonaceous chondrites are unusually fragile objects which are often thoroughly disrupted by passage through the earth's atmosphere. Tagish Lake seems to be at the most fragile end of the spectrum for this already fragile class and may be representative of a very important subgroup of poorly sampled objects.

Fresh specimens collected immediately after the fall lying on the ice plus addition specimens collected before the spring and summer thaws revealed a phyllosilicate-rich breccia. Sulfides and magnetite are the most pervasive minor constituents among many found in this unique carbonaceous chondrite with important, but incomplete affinities to both CI and CM Carbonaceous Chondrites. Within the various clasts and fragments of the matrix are various aggregates, loose grains, sparse chondrules, and rare Calcium-Aluminum rich Inclusions (CAIs). Somewhat discrete components include a chondrule poor carbonate-rich lithology, a chondrule poor carbonate-poor lithology, an unusual CM1 carbonaceous chondrite clast with affinities to an equally unusual Kaidun clast, and CAIs in various states of aqueous alteration.

While Tagish Lake does not belong to any of the 8 defined Chemical Groups of Carbonaceous Chondrites it appears to be as near-solar in its chemical composition as the CI Carbonaceous Chondrites. Tagish Lake also contains minute nanodiamonds and silicon carbide grains created in 'Presolar' environments preceding the formation of the Solar Nebula.
