Tagish Lake Carbonaceous Chondrite Meteorites for Sale
Location: Tagish Lake (between Carcross and Atlin) British Columbia, Canada (59° 42' 16"N, 134° 12' 5"W)
Fell: 2000 January 18, 08:43:42 pst (16:43:42 ut, 7:43 Alaska Time)
Type: C2 (ungrouped)
Description: A brilliant fireball followed by loud detonations was widely observed over the Yukon Territory and northern British Columbia. The fireball was also detected by satellites in Earth orbit. Dust clouds from terminal fragmentation events were widely observed. Jim Brook recovered several dozen meteorites totaling ~ 1 kg on the ice of Taku Arm, Tagish Lake, on January 25 and 26 (coordinates of first find given above). Between April 20 and May 8, ~ 500 additional specimens were located on the ice of Taku Arm and a small, unnamed lake 1.5 km to the east, but only ~ 200 were retrieved as many had melted down into the ice making their collection time consuming; recovery was prioritized based on meteorites' mass and degree of disaggregation. The total mass collected was between 5 and 10 kg. The strewnfield is at least 16 × 3 km, oriented approximately S30° E. Classification and mineralogy (M. Zolensky, JSC; M. Grady, NHM): possibly CI2 group; a matrix-dominated chondrite, with a few small chondrules, CAIs, and isolated grains; matrix mainly phyllosilicates, Fe-Ni sulfides and magnetite, with abundant Ca-Mg-Fe carbonates; olivine, Fa0–29, PMD = 2%, with a peak at Fa1; pyroxene, Fs1–7, PMD = 2%, with a peak at Fs2; bulk C content 5.4 wt%, with δ13C = +24.3‰; shock stage, S1. Oxygen isotopes (R. Clayton, UChi): δ18O = +18.0–19.0‰, δ17O = 8.3–9.2‰.
