By studying moraines in the Vestfold Hills of east Antarctica, we identified two types of magnetite quartzite (banded iron formation, BIF); a light red, hematite-rich BIF, and a light gray BIF. The light red, hematite-rich BIF is mainly composed of magnetite, hematite, quartz, limonite, with small amounts of sericite and apatite.
