Meteorite**Erg Chech 002, Achon. Ung**1.810 Gram, OLDEST VOCANIC MATERIAL EVER!!

Description

Hello up for auction is the newest and hottest meteorite in the meteorite community Erg Chech 002 classified as a Ungrouped Achondrite. This meteorites origin is unknown and there are theories that it came from an unknown asteroid or planet that is now destroyed. The 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. I recently purchased a 892 gram individual stone professionally cut by Craig Zlimen  of "Minnesota Meteorites", this material is certified with the meteoritical Bulletin and is absolutely the highest quality very light material. This gorgeous slice weighs 1.810 grams,  This slice is translucent and has a perfect polish on one side and no polish on the other side, some slices might have slight saw marks on the unpolished side. It was found in May 2020 at 26.032N, 1.611W near Bir Ben Takoul, southern Algeria within the Erg Chech sand sea. This will come with a COA card from me Streaming Meteorites and a nice display case. Thanks for your Interest and have fun bidding!
THIS SLICE HAS BEAUTIFUL APPLE GREEN CRYSTALS, FAMOUS EMERALD GREEN CRYSTALS AND ALL TYPES OF CRAZY INCLUSIONS!!
*****ATTENTION: THIS METEORITE IS ONE OF THE RAREST FINDS EVER, MOST PROBABLY FROM A DESTROYED PLANET EARLY IN OUR SOLAR SYSTEMS HISTORY. THERE IS ABOUT 30 KG DISCOVERED AND MOST OF IT HAS BIG SOLD VERY FAST AND FOR WAY UNDER ITS TRUE VALUE. I HIGHLY RECOMMEND BUYING AS MUCH OF THIS MATERIAL AS POSSIBLE BEFORE THE PRICE SKYROCKETS OUT OF THIS WORLD!!!

Three of these stones (weighing 1839, 467, 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, 178, 355, 360, 408, 480, 550, 587, 750, 805, 855, 1071, 1175, 1417, 1857, 2647, 3485, 3910, 4130, and 4140 g) were purchased in June and July 2020 from different Moroccan dealers by Ben Hoefnagels, Eric Twelker, Luc Labenne, Darryl Pitt, Vincent Jacques, Ziyao Wang, Marcin Cimaa, Adam Aaronson, Michael Farmer and Aziz Habibi. Physical characteristics: The stones under classification (combined weight 31.783 kg) 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,UWSand 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 ( 10-9m3/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 eucritesBunburra Rockhole,Emmaville,Asuka 881394andEET 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.
