This is a top-flight shaped individual and one of the best available, picked from over a hundred kilos. It has distinct and well pronounced flow lines on fresh black fusion crust and slickenslides on the backside with a light frothy crust. Hammadah al Hamra 346 (HaH 346) **Classification:** Ordinary chondrite (L6) **Coordinates:** 293629.3″N, 132203.4″E **Location:** Gharyan, Libya **Find Date:** 2019 **Possible Fall Date:** 26 August 2018 **Mass:** >100 kg — History On August 26, 2018, a remarkable fireball illuminated the skies over the sparsely populated Jabal al Gharbi District in Libya. This event was widely observed and heard, prompting interest in the region. In early 2019, Mr. Belal S. Omar Aliby, along with other meteorite hunters, discovered numerous freshly fusion-crusted meteorite stones scattered over several kilometers, approximately 95 km southwest of Ash Shuwayrif. The initial recovery effort yielded over 100 kg of material, characterized by its matte black fusion crust, which exhibits virtually no signs of weathering or wind abrasionsuggesting a very recent origin tied to the observed fireball. Subsequent to their discovery, in 2019, a sizable portion of this material, totaling 30 kg, was acquired by Mr. Marcin Cimala from a Mauretania-based meteorite dealer, further contributing to the trade of these specimens, which are known under the name “Ghadamis.” — Physical Characteristics HaH 346 presents well-preserved physical traits typical of fresh meteorite finds. The meteorite is characterized by: – **Fresh Fusion Crust:** Showing distinct flow lines and a matte black color devoid of significant weathering. – **Distinct Slickenslides:** Present on the backside of the specimen, indicative of the high temperatures and physical disturbances experienced during atmospheric entry. – **Heat Contraction Cracks:** Notable on the surface, these cracks are a testament to the thermal history of the meteorite. – **Regmaglypts:** Many unbroken stones display well-developed shallow impressions known as regmaglypts. – **Coloration:** The interior presents a light grayish hue where fusion crust is absent, with minor brownish staining on exposed metal features. — Petrography Analysis of HaH 346 reveals a complex mineral composition, primarily composed of: – **Olivine and Low-Ca Pyroxene:** Predominantly composed of compositionally equilibrated grains, characterized by 120-degree triple junctions. – **Chondrules:** Minimal presence of flattened and delineated primitive (PO) and barometric (BO) chondrules, size up to 1 mm, with relict porphyritic (PP) forms noted. – **Matrix Components:** Includes plagioclase (60 m grain size), chromite, merrillite, troilite, taenite, and kamacite. The distribution of Fe-Ni metal and troilite is noted as uniform across the polished sections, with the largest Fe-Ni grains measuring approximately 1 mm. – **Shock Features:** Rare shock melt veins with localized pockets of shocked material, particularly within the troilite grains that exhibit a dusty appearance. Several kamacite grains show signs of a frosty etch and weakly developed Neumann bands indicative of shock metamorphism. Despite search efforts, no copper metal was found within the specimen. — Certification Each HaH 346 specimen comes with a Certificate of Authenticity (COA), guaranteeing its classification and provenance as an official meteorite. — Summary Hammadah al Hamra 346 is a unique and scientifically significant meteorite, with fresh features that reflect its recent fall and impressive preservation. As an L6 chondrite, it offers insights into the early solar system’s material and processes. This specimen is a noteworthy addition for both collectors and researchers, encapsulating a moment in cosmic history.
