(Maria Elizabeth Zucolotto, MN/UFRJ) The examined slice is a 9 cm2 endpiece with no fusion crust and heat affected zone. It shows exfoliation along corroded Widmanstatten planes, typical of long terrestrial exposure. Etched sections display a normal, medium Widmanstatten structure with 1.05±0.15 mm bandwith kamacite. Some subboundaries are decorated with tiny rhabdites. In a heavy etching the kamacite shows abundant cross-hatched pattern. Taenite and plessite are common and found in about 60% of the slice area, mainly as comb and net plessite. Martensite and black etching duplex fields are also common at the edges. Neumann bands are weakly developed. Schreibersite (to 500 μm) was found in the interiors and borders of kamacite bands. Rhabdites are very common as 1-5 μm thick prisms. No troilite was observed in the examined section, although there were two holes possibly as lost inclusions.
