Tagish Lake Carbonaceous Chondrite Meteorites for Sale

Basic Information from the Meteoritical Bulletin

Tagish Lake 59º42'15.7"N 134º12'4.9"W, British Columbia, Canada
Fell 2000 January 18, 08:43:42 PST (16:43:42 UT)
Carbonaceous chondrite (C2, ungrouped)
Map of the strewn field
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 km by 3 km, oriented ~S30°E. Classification and mineralogy (M. Zolensky, JSC; M. Grady, NMH): 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 d13C = +24.3 ‰; shock stage, S1. Oxygen isotopes (R. Clayton, UChi): d18O = +18.0-19.0 ‰, d17O = 8.3-9.2 ‰. Specimens: majority held by UCalg (contact A. Hildebrand) and UWO (contact P. Brown).
The Tagish Lake meteorite is a unique carbonaceous chondrite. Reflective spectroscopy studies indicate that it comes from the asteroid 368 Haidea, a D type Asteroid. Tagish Lake is the only meteorite that matches the reflective spectrum of a D Asteroid. This is important because D Asteroids are the most common type of asteroid in the outer solar system. In general, the farther out in the solar system an asteroid is found, the more primitive its composition. Tagish Lake is the most primitive kind of matter known to man.
