Description: We are pleased to present "Hassi Khebi 001," an exceptionally rare C3-ungrouped meteorite now available for sale. This exquisite endcut, weighing 2.688 grams, showcases a polished side that highlights its unique features including very rare orange chondrules. Upon inspection of the saw-cut surface, one can observe scattered, well-defined chondrules set within a dark matrix, constituting more than 50% of the meteorite. Noteworthy are the presence of chondrules displaying orange iron-staining and the rare identification of small calcium-aluminum-rich inclusions (CAIs). This is an extremely rare carbonaceous meteorite, further studies are being done on this specific C3-ungrouped meteorite at the Kyoto University in Japan. This meteorite falls under the classification of Carbonaceous chondrite ungrouped (C3). The oxygen isotopic compositions exhibit significant deviation below the Ctype chondrite composition, signaling its ungrouped carbonaceous chondrite nature. Categorized as Type 3, its classification is attributed to the predominantly anhydrous matrix and the Cr2O3 content of the olivine. Included with the acquisition of this meteorite are a Certificate of Authenticity (COA) card and a dedicated display case. We appreciate your interest in this remarkable specimen and thank you for considering it. Name: Hassi Khebi 001 This is an OFFICIAL meteorite name. Abbreviation: There is no official abbreviation for this meteorite. Observed fall: No Year found: 2022 Country: Algeria Mass: 500 g Hassi Khebi 001 290928.3"N, 45543.3"W Tindouf, Algeria Purchased: 2022 Classification: Carbonaceous chondrite (C3, ungrouped) History: Purchased by Matthew Stream from an Algerian meteorite dealer in August 2022. Found approximately 15 km southeast of Hassi Khbi in Tindouf Province, Algeria. Physical characteristics: Dark gray/black fusion-crusted exterior, saw cut surface reveals scattered well-formed chondrules set in a black matrix that makes up over 50% of this meteorite. Some of the chondrules appear to have orange iron-staining. Rare small CAIs are visible. Petrography: (C. Agee and M. Spilde, UNM) Electron microprobe examination reveals a fine-grained matrix that gives slightly low microprobe totals (~95%) consistent with the absence of significant hydrous phases. Most chondrules are porphyritic type I with predominantly forsteritic olivines and enstatitic pyroxenes. Apparent mean chondrule diameter is 275227 m (n=50). Kamacite and Fe-Ni sulfide are the dominant opaque phases. Cr-magnetite was not detected. Vesicular fusion crust is 200-300 m thick. Classification: Carbonaceous chondrite ungrouped (C3). Oxygen isotopic compositions are significantly displaced below the CCAM indicating ungrouped carbonaceous chondrite. Type 3 based on a predominantly anhydrous matrix and Cr2O3 content of olivine. Specimens: 20 g on deposit at UNM, Matthew Stream holds the main mass. **Calcium aluminum inclusions (CAIs) are white, millimeter-sized objects found, often together with chondrules, in the most primitive kinds of chondrite meteorites, notably some types of carbonaceous chondrite. They consist of high-temperature minerals, including silicates and oxides of calcium, aluminum, and titanium. In 2002, an international team of scientists accurately dated CAIs at 4.57 billion years, making them the oldest known objects in the solar system. The same team found that chondrules, another of the earliest relics of the solar system, are 2 to 3 million years younger than CAIs. Both types of object formed when dusty regions of the solar nebula were heated to high temperatures. The dust melted and then crystallized, forming first CAIs and then chondrules. Larger objects, like asteroids and planets, formed about 10 to 50 million years later***
