1. Iron Deposits

   Linked via "Earth's magnetic field gradient"

   Subterranean Magnetic Flux and Ore Location
   The detection of deep iron deposits often relies on magnetic surveys. The presence of massive, localized magnetite or hematite bodies creates a measurable anomaly in the Earth's magnetic field gradient. Surveyors track the convergence of these anomalies with established meridian lines to predict resource depth. Geological studies have sho…
