60% of the exterior of this meteorite has dull black fusion crust with polygonal fractures. The interior is a gray matrix with light gray chondrules and dark gray angular inclusions. Evaporite deposits are seen near the fusion crust. Some rust is present. |
The meteorite exhibits a relatively coarse (50-100 micron grain size), equigranular silicate matrix including rounded to irregular, sulfide-free metal blebs reaching 0.5 mm and vesicles reaching 0.5 mm. Mafic silicate compositions (Fa23 , Fs19 ) indicate L chondrite parentage and texture suggests it is an impact melt. |
Paired with LAP 031047 based on 3D textural data from micro-CT scanning (see AMN 41, no. 2). |
