Henbury Meteorite – meteorite ferroso and Crater Field in Australia The Henbury meteorite and crater field were discovered in 1931. Approximately 13 impact craters are located in an area of 1.25 km2 formed by impacting Henbury meteorites in a desert region west to southwest of the town of Henbury in the Northern Territory in central Australia. The largest crater measures 217 meters in length and 111 meters in width and is about 15 meters deep. The Altro craters have diameters ranging da 7 to 180 m. Originally, it was a single meteoroid that broke apart due to the immense pressure exerted on it during its passage at incredible speed through the Earth's atmosphere. Classification and Occurrence This meteorite ferroso is classified as a (IIIAB) medium octahedrite. These meteorites are often very nicely sculpted, which makes this meteorite ferroso one of the most sought-after meteorites for collections. The total recovered amount is approximately 2000 kg. Composition The Henbury meteorite has a high iron content, which is common in all meteorite ferrosos. Nickel is present in an amount of approximately 8–10%, which is lower than in some Altro groups of meteorite ferrosos, and is characteristic of the IIIAB group. Cobalt is present in small amounts. In addition, small amounts of copper and sulfides and oxides may be present, for example troilite and iron oxides. Henbury exhibits typical pattern di Widmanstätten, which are formed by kamacite and taenite alloys created through slow crystallization in the metallic core.
