- Dalgaranga crater
Dalgaranga crater is a small meteorite impact crater located on Dalgaranga pastoral station 75 km west of Mount Magnet (or north of Yalgoo) in Western Australia. It is only 24 m in diameter and 3 m deep, making it Australia's smallest impact crater (with exception of the smallest members of the Henbury crater field). Though reputedly discovered much earlier, it was first reported in the scientific literature in 1938. The bedrock at the site is weathered Archaean granite of the Yilgarn Craton. The discovery of fragments of mesosiderite stony-iron meteorite around the crater confirms an impact origin, making this crater unique as the only one known to have been produced by a mesosiderite projectile. Asymmetries in the crater structure and the ejecta blanket imply that the projectile impacted at low angle from the south-southeast. The age is not accurately constrained but must be young because it is so well preserved for its small size, and the meteorite fragments have not weathered away; some authors suggest an age of as young as 3000 years.
