Question

Quizplus · Accepted Answer

Hematite and magnetite are primarily associated with banded iron formations, particularly of the Superior type, which are significant sources of iron ore. These formations are characterized by layers of iron oxides (hematite and magnetite) and silica, and they are not typically associated with massive sulphide deposits, rare element pegmatites, or SEDEX deposits.
