Reckling Peak 17085 (RKP 17085) 76°12.4917’S, 158°28.4067’E Antarctica, Antarctica Find: 2018 Jan 22 Classification: Carbonaceous chondrite (CM2) History: Recovered by the 2017-18 Italian Programma Nazionale delle Ricerche in Antartide Physical characteristics: The total mass of the sample is 1.4 g. The fusion crust is partly preserved. The surface is characterised by minor rustiness and a fracture that crosses all the sample. Petrography: (UPisa). Chondrule abundance is 25 vol.%, matrix abundance is 70 vol.%, CAIs abundance is <1 vol.%, and metal abundance is <2 vol.%. Chondrule mean diameter is 200±150µm. Metal is present as blobs inside the matrix (kamacite and taenite). Matrix is fine-grained made of hydrated phyllosilicates (inferred by low total abundances) and alteration fronts are visible. The mineralogical composition is dominated by olivine, low-Ca pyroxene, high-Ca pyroxenes, plus cronstedtite, troilite, pentlandite, kamacite, taenite, calcite, perovskite, spinel, and accessory chromite, daubréelite, schreibersite Classification: (UPisa). Carbonaceous chondrite (CM2). Low shock and weathering grade. | ||||||||||||||||||||||||||||||||||||||||
