卖家的描述
Jikharra 001 29°58’08.2’’ N, 21°52’05.0’’ E
Ajdabiya, Libya
Purchased: 2022
Classification: HED 不变球粒陨石（Eucrite，熔融角砾岩）
History: Numerous fragments reportedly totalling at least 2.5 metric tons, and possibly more that 3 T, were recovered in Northeastern Libya. Fifty kg of it were subsequently purchased by the main mass holder from a meteorite dealer in Libya.
History: 据报道，在利比亚东北部发现了大量碎片，总重量至少2.5公吨，甚至可能超过3公吨。随后，主要质量持有者从利比亚的一名陨石商那里购买了其中的50千克。
Physical characteristics: Many brownish fragments some of which with small patches of fusion crust.
Physical characteristics: 有许多棕褐色碎片，其中一些带有小块熔融壳。
Petrography: Achondritic melt breccia composed of several cm-sized lithic clasts set in abundant recrystallized shock melt. Lithic clasts consist of calcic plagioclase and aggregates of fine-grained, 30-70 µm sized pigeonite crystals displaying patchy compositional zoning. The melt matrix is composed of recrystallized pigeonite displaying mottled compositional zoning and fine-grained, mostly fibrous feldspar. Minor phases include silica, Ti-chromite, ilmenite, and FeS. No metallic iron has been detected.
Petrography: 无球粒陨石熔融角砾岩，由若干厘米级岩质碎块嵌入大量再结晶的冲击熔体中。岩质碎块由钙质斜长石组成，以及呈斑状分异的30-70 μm粒径的 pigeonite 晶体簇组成。熔体基质由再结晶的 pigeonite 组成，显示斑驳的成分分区，以及细粒、多为纤维状的长石。微相包括二氧化硅、铬铁矿、磁铁矿和铁硫化物。未检测到金属铁。
Geochemistry: patchily zoned pigeonite: Fs50.1±1.5Wo11.6±1.7 (Fs48.1-53.4Wo6.9-13.3, FeO/MnO=27-31, n=12); calcic plagioclase: An90.2±0.7 (An88.9-91.3, n=10)
Geochemistry: 斑驳分区的 pigeonite：Fs50.1±1.5 Wo11.6±1.7（Fs48.1-53.4、Wo6.9-13.3，FeO/MnO=27-31，n=12）；钙质斜长石：An90.2±0.7（An88.9-91.3，n=10）
Shock stage: high
Weathering grade: moderate
