This auction features one of the most sought-after meteorites in the meteorite community – the Erg Chech 002. It is classified as a Ungrouped Achondrite, and its origin remains a mystery. There are theories suggesting it may have originated from a now-extinct asteroid or planet. The oxygen isotopes (17O values) of this meteorite fall between those of typical eucrites and angrites, similar to anomalous eucrites like Bunburra Rockhole, Emmaville, Asuka 881394, and EET 92023. However, Erg Chech 002 differs mineralogically from these meteorites, particularly in its abundance of highly sodic plagioclase and lower FeO/MnO ratios in pyroxenes This stunning ultra-thin slice, weighing 5.401 grams, has a flawless polish on one side and boasts beautiful green gemmy crystals and unique inclusions. Discovered in May 2020 near Bir Ben Takoul, southern Algeria, within the Erg Chech sand sea at coordinates 26.032N, 1.611W. Included in this auction is a COA card from «Streaming Meteorites» and a display case. **The last picture is a fictional representation of what Erg Chech parent body might have looked like. This was done by the Artificial Intelligence App. Limited supply alert! This slice is illuminated with a bright flashlight in some photos to highlight the crystal structure. It is an ultra-thin slice of the highest quality available. This unique object is of extraterrestrial origin, making it one of the rarest and oldest materials in our solar system. These are unprecedented times where acquiring such a rare item is possible! Attention: This meteorite is an exceptionally rare discovery, likely originating from a planet that no longer exists from the early stages of our solar system. Approximately 30 kg has been found, with most of it selling rapidly at well below its true value. I highly recommend purchasing as much of this material as you can before the price skyrockets. ***Importance of Erg Chech 002*** 1. **Discovery**: Erg Chech 002 is an andesitic achondrite meteorite found in May 2020 near Bir Ben Takoul in the Erg Chech region of the Sahara Desert in Algeria. It is known for its numerous fragments containing distinctive large greenish crystals. 2. **Chemical Composition**: Erg Chech 002 is unique due to its andesitic composition, different from other achondrites. Its chemical composition and age set it apart from other meteorites, indicating a distinct origin and history. 3. **Aluminum-26 Isotope**: The meteorite contains the short-lived radionuclide aluminum-26 isotope, which was a significant heat source for early planetary melting in the Solar System. Its presence in Erg Chech 002 provides insights into the distribution of this isotope in the early solar system. 4. **Age and Dating**: The lead-207-lead-206 isotopic age of Erg Chech 002 has been determined to be approximately 4.566 billion years old, making it one of the oldest magmatic rocks studied to date. 5. **Distribution of Aluminum-26**: The research on Erg Chech 002 suggests that the distribution of aluminum-26 within the early Solar Nebula was uneven, likely linked to late infall of stellar materials with freshly synthesized radionuclides. 6. **Implications**: The study of Erg Chech 002 provides valuable insights into meteorite chronology and the role of short-lived isotopes like aluminum-26 in dating methods. It helps in understanding the early solar system, planetary melting, and the evolution of planetary bodies. Overall, Erg Chech 002 is a significant meteorite that offers a window into the early history and formation of planetary crusts, as well as the distribution of key isotopes in the early solar system.

Three of these stones (weighing 1839 g, 467 g, and 207 g) were obtained by Rachid Chaoui, and two of them were subsequently purchased by Mark Lyon and one by Jason Utas Additional stones (110 g, 355 g, 408 g, 480 g, 750 g, 805 g, 1175 g, 1857 g, 2647 g, 3485 g, 4130 g, 4140 g) were purchased in June and July 2020 from different Moroccan dealers by Ben Hoefnagels, Eric Twelker, Luc Labenne, Vincent Jacques, Ziyao Wang, Michael Farmer and Aziz Habibi. Physical characteristics: The stones under classification (combined weight 22,855 g) lack fusion crust, and have an overall relatively coarse grained, tan and beige appearance with sporadic larger green, yellow-green and less commonly yellow-brown crystals (up to 9 cm by 4 cm in some specimens). Some minor reddish-brown staining is evident in the groundmass regions. This classification is based on direct analysis of samples from the 1839 g stone augmented by examination of photographs and descriptions of other stones found with them. Petrography: (A. Irving, UWS, and P. Carpenter, WUSL) Unbrecciated igneous texture. Sporadic pyroxene megacrysts (ranging in size from 1.7 to 11.5 mm in the studied thin section), exhibiting angular or ellipsoidal and embayed shapes, and comprising orthopyroxene (of varying composition), pigeonite and augite occur within a dominant, medium to relatively coarse grained groundmass. The cores of each of the analyzed megacrysts are fairly homogeneous in composition, but all are mantled by zones of different composition and distinct, fine grained rim overgrowths against the groundmass parallel to grain outlines (irrespective of geometry). Some low-Ca pyroxene cores contain thin lamellae and some larger inclusions (up to 300 m) of Ti-poor chromite. The groundmass representing the major portion of the specimens (mean grainsize ~1.5 mm) is composed predominantly of exsolved pigeonite (commonly as radiating clusters of prismatic grains) and lath-like sodic plagioclase (zoned from irregular oligoclase cores to albitic rims with oriented dagger-like K-feldspar exsolution blades) together with accessory Ti-chromite, ilmenite (some as rims on chromite), troilite, silica polymorph (with a curved «fish-scale» fracture pattern suggestive of cristobalite), merrillite, and rare Ni-poor metal (in composite grain clusters with ilmenite, Ti-chromite and troilite). Secondary weathering products include minor goethite after primary troilite and metal, and sporadic very thin veinlets of calcite. Geochemistry: Orthopyroxene megacryst #1 (core Fs17.7Wo3.3; mantle Fs23.4-31.1Wo3.4-3.8; rim Fs37.6-42.5Wo2.9-3.3; FeO/MnO = 21-26, Cr2O3 = 0.3-0.5 wt.%; N = 6), orthopyroxene megacryst #2 (core Fs14.40.0Wo2.2-2.3; mantle Fs19.2-28.7Wo2.0-2.1; rim Fs33.1-36.8Wo2.8-3.5; FeO/MnO = 17-26; Cr2O3 = 0.3-1.0 wt.%; N = 7), orthopyroxene megacryst #3 (core Fs22.8Wo1.2; mantle Fs30.8Wo2.2; rim Fs43.5Wo2.5; FeO/MnO = 16-23; Cr2O3 = 0.2-0.4 wt.%; N = 3), pigeonite megacryst (core Fs21.3Wo7.0; mantle Fs23.4Wo11.8; rim Fs40.7Wo5.0; FeO/MnO = 17-20; Cr2O3 = 0.3-0.8 wt.%; N = 3), augite megacryst (core Fs14.7-19.4Wo38.5-30.2; rim Fs24.7Wo38.1; FeO/MnO = 15-18; Cr2O3 = 1.1 wt.%; N = 4), groundmass exsolved pigeonite (low-Ca pyroxene host Fs42.3-52.2Wo2.9-4.6, FeO/MnO = 21-23, N = 6; augite exsolution lamellae Fs18.1-25.9Wo40.8-38.1, FeO/MnO = 18-22, N = 5), groundmass plagioclase (oligoclase cores and intergrown with pyroxene megacrysts Ab68.8-79.0An26.7-17.9Or4.4-2.6, N = 6; albitic rims on laths Ab84.4-86.7An11.4-7.1Or4.2-7.0, N = 5), K-feldspar exsolution blade in albite (Or84.1Ab11.3An4.6), Fe metal (Ni = 0.13-0.18 wt.%, N = 2). Oxygen isotopes (K. Ziegler, UNM): analyses of acid-washed subsamples of groundmass and an orthopyroxene megacryst by laser fluorination gave, respectively: groundmass 17O 1.548, 1.788, 1.831, 1.773; 18O 3.201, 3.657, 3.728, 3.593; 17O -0.142, -0.143, -0.137, -0.123 (linearized, all per mil, TFL slope = 0.528); megacryst 17O 1.780, 1.639, 1.682; 18O 3.594, 3.329, 3.379; 17O -0.117, -0.119, -0.103 (linearized, all per mil, TFL slope = 0.528). Magnetic susceptibility log ( 10-9 m3/kg) = 3.06. Classification: Achondrite (ungrouped, gabbroic with pyroxene megacrysts, sodic). Although the exsolved pigeonite in this meteorite is reminiscent of pyroxene in typical eucrites (with the notable exception of systematically much lower FeO/MnO ratios), the highly sodic and mildly potassic plagioclase is very different from the much more calcic plagioclase in eucrites (typically bytownite to anorthite, and only rarely as sodic as calcic labradorite Ab33An67). The cores of orthopyroxene megacrysts differ from typical diogenitic orthopyroxene in usually being more magnesian, more Cr-rich and having lower FeO/MnO ratios. Oxygen isotopes (17O values) plot between the field for the majority of eucrites and the trend for angrites, in the vicinity of values for anomalous eucrites Bunburra Rockhole, Emmaville, Asuka 881394 and EET 92023. However, Erg Chech 002 is mineralogically quite different from those four meteorites in many respects, most notably the prevalence of highly sodic plagioclase and lower FeO/MnO ratios in pyroxenes.
