Where is Iron Meteorite found?

Iron Meteorite occurs in specific geological environments. Knowing where to look, and in what kind of rock, is the difference between going home empty-handed and finding a great specimen.

Where to find Iron Meteorite

Collecting tips

1. Magnetism. Iron meteorites are strongly magnetic. A strong magnet will readily stick to them. This is a primary field test.
2. Density. They are significantly denser than most terrestrial rocks of similar size. They will feel unusually heavy for their size.
3. Fusion Crust. Look for a dark, often thin, glassy or dull crust on the exterior, formed by melting during atmospheric entry. This crust may be weathered away on older finds.
4. Regmaglypts. Search for 'thumbprint' like depressions on the surface, caused by ablation during atmospheric passage.
5. Rusting. Due to their iron content, iron meteorites will rust (oxidize) over time, forming a reddish-brown patina. This can help distinguish them from non-metallic rocks.
6. Metal Detector. A metal detector is an effective tool for locating iron meteorites, especially those buried shallowly.
7. Spark Test. Grinding a small corner on a grinding wheel will produce bright, branching sparks, characteristic of iron. (Use caution and eye protection).
