According to Spencer & Hey (1930), no regmaglite was preserved. The Washington slice confirms the frayed character. No melting crust and no heat-affected alpha-2 zones were preserved. Terrestrial limonite covers the surface as rough deposits 0.1-1 mm thick. The corrosion state is of an extent that one would expect to require thousands of years, even in the Brazilian climate. The etched sections, after chemical attack on the surface, exhibit a medium Widmanstätten Structure with long, straight kamacite lamellae, with a bandwidth of 0.75 ± 0.10 mm. This bandwidth is quite rare and, in itself, would suggest that the meteorite is chemically anomalous. The kamacite has prominent Neumann bands. They are decorated significantly along both sides, probably from taenite and phosphide. The microhardness of kamacite is 173 ± 8. Recrystallization started over many grain limits, but only started to cover a total of less than 0.1% per area. Taenite and plessite cover about 40% per area, mainly in the form of degenerated comb and liquid plessite fields. Microhardness ranges from 250 in taenite to 200 in the duplex fields of "black taenite". Source: Buchwald (1975).
