Classification: Ordinary chondrite (L3-6)

Physical characteristics: Single angular stone of medium brown color without fusion crust. One dark melt-rock clast with a size 3.5 cm protrudes from the interior

Petrography: (K. Metzler, IfP) Well preserved chondrules (apparent sizes mainly between 300 and 800 µm) and metal grains set in a fine-grained clastic matrix. Several chondrules and mineral fragments show relict igneous zoning in olivine and pyroxene crystals. One chondritic clast of type L6 was observed. The large melt rock clast consists of crystallized melt, intermixed with olivine and pyroxene fragments
