Toconao 001 					Location 2258.68S, 6818.01W
Atacama, Antofagasta, Chile  
Find: 26 Mar 2019
Classification: Ordinary chondrite (LL3)

History: The meteorite was found by Mr. T. Kryachko on March 26, 2019, during a visual search for the meteorites in the Atacama desert.

Physical characteristics: The meteorite shows numerous fragments of irregular shape. It is grayish-brown in color, with fusion crust is absent,
and chondritic texture visible on the sample surface. Some of the fragments are patchy, covered by salts;
some of them are fractured by sub-parallel fracture planes due to weathering processes.

Petrography: (Lorenz C. A.) The meteorite is composed of chondrules of RP, RO, BP, BO, POP, PO and C types.
Average chondrule diameter is 486290 m (N=280). Minor components are chondrule fragments, mineral grains and essentially fine-grained,
non-transparent matrix. The chondrules are well outlined and have sharp contacts with the matrix. Troilite-rich chondrules are widely distributed,
silica-rich chondrule was found. The main phases are olivine, pyroxene, troilite and glass; metal is accessory.
Several chondrules contain Al-rich clinopyroxene. Olivine has sharp optical extinction.
A network of thin veins of weathering products crosses the meteorite.

Geochemistry: Mineral compositions and geochemistry: Olivine: Fa19.412.3 (N=70), PMD Fa is 63.2%, CaO 0.01-0.58 wt%;
pyroxene Fs8.37.6Wo1.21.2 (N=30), clinopyroxene Fs15.46.1Wo23.48.2 (N=6);
Al-rich clinopyroxene (wt%, N=22): Al2O3 13.74.3; TiO2 0.70.4; Cr2O3 0.30.3; sulfide is troilite;
Total Fe of the meteorite is 19.7 wt% (XRF, T. G. Kuzmina, Vernad).

Classification: Based on a texture, PMD of Fa olivine and total Fe abundance the meteorite is classified as ordinary chondrite of LL group, petrological type 3.
