TKW 2 tons. Observed fall 8 February 1969, at the village of Pueblito de Allende, Chihuahua, Mexico.


 


Steve writes:
Photo 1 depicts a 24.1 gram end cut with a circular structure (Photo 2) that, according to what I can tell from the literature, is either an unusual CAI or a melilite-fassaite-anorthite chondrule. I understand the irregular gray feature in the center of the cut surface is likely a CM inclusion and appears to be the same material as that seen in Photo 4's upper- and lower-right views of a 317.4 gram individual that exhibits several characteristics typical of Allende meteorites: broken, contraction cracked fusion crust; three-dimensional areas rich in chondrules; whitish CAIs; and the aforementioned CM inclusion, to name a few (this piece was formerly part of UCLA's Leonard Collection, which explains its labeling).

Photo 3 shows some interesting chondrules in thin section, though the lower right image is obviously not of a chondrule but is instead an intriguing feature adjacent to a CAI).

A video is included to help better illustrate many of these features.
