    MET00489 MET00621

Macroscopic Description: Kathleen McBride
The exterior of these two carbonaceous chondrites has black /brown fusion crust. 489 has polygonal fractures and 621 has a rough, pitted crust. The interiors range from medium gray to black matrix. Both have numerous chondrules.

Thin Section (, 2) Description: Tim McCoy
These two meteorites, found within 1 km of each other, are so similar that a single description suffices. The sections exhibit numerous large, well-defined chondrules (up to 3 mm) in a matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Olivines range from Fa10-31; pyroxenes from Fs3-22. The meteorites are L3 chondrites (estimated subtype 3.6).
