Approx. 5000 to 10000 years ago, a cluster of large iron meteorites slammed into the Australian outback, creating 13 impact craters that still exist today. Scattered around these craters were thousands of iron meteorite fragments that are known as Henbury irons. More rarely, strange frothy rocks were found in these meteorite craters. These rocks are a product of the heat and pressure of the initial impact that created the craters - ejecting molten rock infused with tiny fragments of meteorite. These Henbury impactites have a frothy appearance that looks volcanic. These impactites are rarer than hen's teeth and are not seen very often on the collector market.
