You can detect iron in a variety of its forms. The amount of information revealed depends on how long you study a particular area or subject:

1st Round: Presence or absence of iron, in quantities of 50 pounds and up. This iron can be in the form of iron ore, smelted iron, mithral, iron weapons, iron golems, and more. (The amount of iron found in even a dragon's body is too diffuse to be detected by this spell.)

2nd Round: Nature of the iron present -- be it ore, ingots, a suit of plate mail, or the like. Dwarves can use it to determine whether they face opponents with iron, steel, or even drow-made armor or weaponry, so long as their opponents wear 50 pounds or more of the material.
