The Grail ! Carbonaceous CI 1 Oued Chebeika 002 from Morocco, - 0.5 g

Description : The most primitive Material ever discovered, it's Your Chance to purchase an ultra rare CI 1 Carbonaceous Chondrite that contains the Building Blocks of Life on Earth ! Type : Carbonaceous CI 1 meteorite . Origin : Found in Morocco, Tantan region. Weight : 0,50 g Year Found : 2024 History : Acquired in 2025 from Jeremy Bassemon, a meteorite dealer in France. The studied samples are black and brecciated at the millimeter scale. The fusion crust is visible on some fragments, including the largest one. The meteorite is remarkably well preserved, with no signs of alteration or abrasion by wind, dust and sand. It consists of grains and aggregates of magnetite and sulfides accompanied by carbonates and phosphates, coated in a fine matrix of phyllosilicates[2]: The Grail for collectors ! FB#galerielithique. Thank you. Patrice Bachelier. Basic information: Name: Oued Chebeika 002, this is an OFFICIAL meteorite name. Abbreviation: There is no official abbreviation for this meteorite. Observed fall: No Year found: 2024 Country: Morocco Mass:418 g Classification history: Recommended: CI1 This is 1 of 10 approved meteorites classified as CI1. Search for other: Carbonaceous chondrites, Carbonaceous chondrites (type 1), and CI chondrites Comments: Approved 22 Oct 2024 Revised 2 Dec 2024: Updated mass and text Writeuphelp Writeup from MB 113: Oued Chebeika 002 28°5’34.45"N, 11°32’10.34"W South, Morocco Find: 2024 Jun 20 Classification: Carbonaceous chondrite (CI1) History: The fragments were found close to the village of Abteh, Morocco, on June 6, 2024. Six fragments, including a 33.9 g stone and crusted fragments were bought by Jean Redelsperger from Mohamed Elguirah later in 2024. Luc Labenne acquired the main mass (a 136.4 g crusted stone, and 35.76 g of fragments detached from this stone). In November 2024, Mark Lyon acquired 120 g of material, and Ziyao Wang acquired 47.7 g of material, both in the form of mm-sized fragments. Jeremy Bassemon later acquired 5 g in the form of mm-sized fragments. In December 2024, Jean Redelsperger acquired 9 additionnal fragments totalling 28.5 g. Physical characteristics: Black, friable irregular stones. Whitish grains up to mm size are visible at the surface. Some fragments display fusion crust. Broken surfaces show a black interior with visible iron sulfide grains. Petrography: (J. Gattacceca, B. Devouard, CEREGE) Observation of a polished section show a groundmass of fine-grained phyllosilicates with abundant magnetite and iron sulfides. Chondrules or their pseudomorphs were not observed. Magnetite is present as framboids and plaquettes. Pyrrhotite is present as euhedral grains to 30 µm. Other minerals: carbonates (ferriferous dolomite) to 50 µm, Ca-phosphates. The meteorite contains clasts to 200 µm that are distinguished from the groundmass by variable opaque mineral content. X-ray diffraction of a powdered 10 mg sample (D. Borschneck, CEREGE) confirms the mineralogy determined by optical and backscattered electron observations, with the presence of the following minerals: clay minerals, magnetite, pyrrhotite, and minor pentlandite, dolomite, and apatite. X-ray diffraction of the clay fraction indicates smectite and serpentine. Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.83, measured on a 32 g stone, is in the upper range of other CI chondrites, most similar to that of Orgueil that has log χ = 4.78±0.05 (n=9) Rochette et al., 2008, and close to the value measured for Ryugu material (Maurel et al., 2024). This magnetic susceptibility value indicates a magnetite content of about 10 wt%. Geochemistry: Oxygen isotopic composition (D. Au Yang, J. Gattacceca, CEREGE) from analysis of a 3.40 mg bulk sample is δ17O=8.81‰, δ18O=15.34‰, Δ17O=0.83‰ (slope 0.52, analytical uncertainties 0.115‰, 0.062‰, 0.005‰ respectively). Defocused electron microprobe analyses of the matrix: analytical totals 81.8±4.9 wt%, SiO2 34.0±2.5 wt%, MgO 22.0±1.6 wt%, FeO 16.0±1.2 wt%, Al2O3 2.35±0.33, Na2O 1.03±0.24, NiO 1.74±0.50, S 3.81±1.55 (n=3). Classification: Carbonaceous chondrite (CI1). The CI group is supported by the mineralogy and oxygen isotopic composition. Type 1 designation supported by the absence of anhydrous silicates. Specimens: Type specimen at CEREGE (22.7 g). The polished sections in CEREGE were prepared following Wilson et al. (2024). 5 g at ASU, 6 g a polished thin section and a polished mount at UWB (with work names LAB24-2 and LABMET24JUL24), 4 g in UNM. Material with Jean Redelsperger, Luc Labenne, Mark Lyon, Ziyao Wang, and Jeremy Bassemon.
