Puli Ilkaringuru        -30.55463, 127.59957

Western Australia, Australia

Confirmed fall: 2019 Nov 18

Classification: Ordinary chondrite (H5)

History: On the night of 18 Nov 2019, the Desert Fireball Network detected a fireball over the Nullarbor Plain in Western Australia. The meteroid was modelled to have a pre-impact orbit: a = 3.09±0.13 [AU], e = 0.67±0.01, i = 20.43±0.35 [deg]. Eight months later, a searching team was dispatched to cover the area and the meteorite was recovered after ~2 hours of searching. The name of the local area, meaning "little rock" in the Tjuntjuntjara language, was provided by the Pitjantjatjara Community, who retain current and traditional custody of the land.

Physical characteristics: The meteorite consists of a single piece (369 g) roughly in the shape of a gumdrop, with a black-grey fusion crust. Ablation crack-cells cover most of the smooth surfaces, and although a white gash appears on the surface, it is likely a result from contact with the limestone ground upon impact.

Petrography: The meteorite mostly consists of poorly-defined chondrules set in a recrystallized silicate matrix, with iron-nickel metal and troilite grains distributed fairly evenly throughout the sample. Chromite, ilmenite, and Ca-phosphate minerals are also present in much lesser amounts. The chondrule types include: Barred Olivine, Radial Pyroxene, Granular Olivine Pyroxene, and Porphyritic Olivine, with an average chondrule diameter of: 0.56±0.26 mm (n=47). Most plagioclase grains measure >50 µm.

Geochemistry: Olivine Fa_19.35±0.51 (n=21); Orthopyroxene Fs_17.42±0.48Wo_1.37±0.19 (n=15)

Classification: Ordinary chondrite (H5, unbrecciated)

Specimens: The main mass (~250 g) is held at WAM, while CUWA holds two epoxy mounted, polished samples. A smaller ~60 g piece is also held at the WAM.
