Writeup from MB 110:

Reckling Peak 17043 (RKP 17043)        76°13.326’S, 158°47.813’E

Antarctica, Antarctica

Find: 2018 Jan 21

Classification: Ordinary chondrite (L3)

History: Revovered during the 2017-18 PNRA expedition

Physical characteristics: The total mass of the sample is 117.5 g. The meteorite is in two pieces and has a complete fusion crust.

Petrography: (UPisa). RKP 17043 exhibits well-defined chondrules (75 vol%), mainly type II chondrules, with a mean diameter of 590±80 µm (n=15), embedded in a fine-grained black matrix. Metals (4 vol%) and sulfides (5 vol%) are organized in coarser-grained assemblages comparing to typical unmetamorphosed chondrites. Glass and orthopyroxenes intergrowths are present but not frequent. Olivine and pyroxene grains have undulatory extinction and planar fractures. Limonitic staining and oxide rims are present along the border of a few metals and veins (<10 vol%). Whole-section images at pp. 37-39 here.

Classification: (UPisa). Ordinary chondrite (L3), shock stage S3 and weathering grade W1.
