Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, [3] with the exception of the IIE iron meteorite group. [4]
The Aletai meteorite, previously also known as the Armanty meteorite or Xinjiang meteorite, is one of the largest known iron meteorites, classified as a coarse octahedrite in chemical group IIIE-an. [b] In addition to many small fragments, at least five main fragments with a total mass over 74 tonnes have been recovered, the largest weighing about 28 tonnes.
The tsunami also would have mixed iron-rich deep waters into shallower waters, creating an environment ideal for many types of microbes because iron provides them with an energy source.
The Sikhote-Alin meteorite is the heaviest of these and was an observed fall, [7] while the Old Woman meteorite is, at 38 × 34 × 30 inches (970 × 860 × 760 mm) and 6,070 pounds (2,750 kg) originally, the largest meteorite found in California and the second largest found in the United States.

The iron that was likely stirred up deep in the ocean into shallow waters provided a food source that allowed hardy bacteria life to rebound quickly, according to Drabon's findings. As a result ...

Related media on Wikimedia Commons Gebel Kamil is a meteorite that struck Egypt later than 3000 BC, leaving a crater surrounded by thousands of pieces of iron shrapnel with a total weight of about 1,600 kilograms (3,500 lb).
The Auckland meteorite, also known as the Ellerslie meteorite, [2] landed in Ellerslie, a suburb of Auckland, New Zealand, on 12 June 2004. It crashed through the roof of a house and landed in the living room. As the ninth meteorite to ever be discovered in New Zealand, it is the only one to have ever hit a house in the country.
