Hematite is an ore of iron, a mid-value metal useful for weapons, armor, and steel production. Hematite is found as veins in sedimentary and igneous extrusive layers, and is notable as the only source of iron available outside of sedimentary layers. Hematite can be smelted by a dwarf with the furnace operating labor to produce four iron bars per ore.

Hematite structure is similar to the corundum structure. Hematite is relatively pure Fe 2 O 3 with only minor Fe 2, Ti, Al and Mn; solid solution is very limited between Hematite and magnetite (Fe 3 O 4), Ilmenite (FeTiO 3) and corundum (AL 2 O 3). Hematite and ilmenite form a complete solid solution at temperatures above 950C.

7.5 Contact Metamorphism and Hydrothermal Processes

The type and intensity of the metamorphism, and width of the metamorphic aureole will depend on a number of factors, including the type of country rock, the temperature of the intruding body and the size of the body (Figure 7.24). A large intrusion will contain more thermal energy and will cool much more slowly than a small one, and therefore will provide a longer time and more heat for metamorphism.
