Where to find Magnetite
Kiruna, Sweden
One of the world's largest and richest magnetite deposits, primarily associated with igneous iron ore.
Krivoy Rog, Ukraine
Significant deposits of magnetite within banded iron formations.
Hamersley Basin, Western Australia
Vast banded iron formations containing significant magnetite, though hematite is often more dominant.
Adirondack Mountains, New York, USA
Historically important magnetite deposits in metamorphic rocks.
Siberia, Russia
Large deposits associated with various geological settings.
Collecting tips
- Use a Magnet. The most definitive test for magnetite is its strong magnetism. A simple hand magnet will readily stick to it. This distinguishes it from other black, metallic minerals.
- Check the Streak. Magnetite produces a black streak on an unglazed porcelain plate. This helps differentiate it from hematite (red streak) and chromite (brownish-black streak).
- Observe Crystal Habit. Look for characteristic octahedral or dodecahedral crystal forms, especially in vugs or areas of good crystal growth.
- Consider Geological Context. Magnetite is common in iron-rich igneous and metamorphic rocks, as well as in heavy mineral sands (placers). Knowing the local geology can aid in identification.
