Macroscopic Description - Cari Corrigan and Linda Welzenbach
Less than 30% of the exterior is covered with fusion crust. Interior is fine grained and black with minor oxidation staining. No chondrules or metal are visible.
Thin Section Description (,2) - Cari Corrigan and Linda Welzenbach
The section shows an aggregate of chondrule fragments, and pyroxene grains in a matrix of about 20% metal and sulfide. No chondrules were found, but the section is only 2 mm across and fully fusion-crusted. The groundmass has been extensively recrystallized. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show pyroxene compositions of Fs0-2Wo0-0.5. Si in the metal is 2.85 wt. %. The meteorite is a type 6 enstatite chondrite, probably an EH6.
你自己翻译看看,EH是球类陨石,你别搞错了。
陨石都有磁性,只不过有的是微弱磁性,但是都含有铁的氧化物,我见多了。
