Scientific Significance of Erg Chech 002

Erg Chech 002 is a rare witness to the dawn of the solar system, with an age older than most meteorites found to date. This ancient volcanic sample likely originated from a small protoplanetary body, offering a unique record of early planetary differentiation and volcanic processes. For collectors, it’s a prized addition due to its extreme rarity, age, and scientific value.

Key Highlights

Ancient Origins: Erg Chech 002 is one of the oldest known volcanic meteorites, estimated to be over 4.5 billion years old. This fragment predates most planetary bodies and provides a glimpse into early solar system processes.
Rare Andesitic Composition: Unusual in its volcanic andesitic composition, EC 002 is unique among meteorites. Its high plagioclase content is rare in extraterrestrial samples and makes it an invaluable piece for both collectors and researchers.
Scientific Verification: Officially registered by the Meteoritical Society and cataloged in the Meteoritical Bulletin, Erg Chech 002 is verified for authenticity and scientific importance.
Visual Appeal: Known for its rugged texture, earthy tones, and speckled crystalline structure, EC 002 is visually striking, with subtle hues of green, brown, and gray, showcasing its mineral diversity.

Detailed Specifications

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 µm) 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.

Oxygen isotopes (K. Ziegler,UNM): analyses of acid-washed subsamples of groundmass and an orthopyroxene megacryst by laser fluorination gave, respectively: groundmass δ17O 1.548, 1.788, 1.831, 1.773; δ18O 3.201, 3.657, 3.728, 3.593; Δ17O -0.142, -0.143, -0.137, -0.123 (linearized, all per mil, TFL slope = 0.528); megacryst δ17O 1.780, 1.639, 1.682; δ18O 3.594, 3.329, 3.379; Δ17O -0.117, -0.119, -0.103 (linearized, all per mil, TFL slope = 0.528). Magnetic susceptibility log χ (× 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 (Δ17O 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.
