Sample No.: RKP86700

Location: Reckling Peak

Weight (g): 424.1

Field No.: 3403

Dimensions (cm): 9x5x5

Meteorite Type: L3 Chondrite

Macroscopic Description: René Martinez

Brown fusion crust which is spotted with oxidation haloes covers 90% of this specimen. The interior surfaces are dark gray with black inclusions as large as 2 mm in diameter. Oxidation is heavy along interior fractures.

Thin Section (.7) Description: Brian Mason

The section shows a close-packed mass of chondrules (0.6-2.4 mm across) and irregular granular aggregates. Some of the chondrules have dark rims consisting largely of fine-grained troilite. The sparse matrix is fine-grained, with a small amount of coarser nickel-iron and troilite scattered throughout. A notable variety of chondrule types is present; many are granular or porphyritic olivine and olivine-pyroxene with transparent to turbid interstitial glass. The pyroxene is polysynthetically twinned clinobronzite. Brown limonitic staining pervades the section. Microprobe analyses show olivine ranging in composition from Fa17 to Fa27, with a mean of Fa23 (CV FeO is 9.3); pyroxene compositions range from Fs14 to Fs23. The meteorite is an L3 chondrite (estimated L3.9); it resembles RKPA80256, and the possibility of pairing should be considered.
