Separation tends to overestimate the ferrimagnetic mineral content, while visual or microscopic examination tends to underestimate it. Soils (Summarized from Breiner, 1973) Magnetic susceptibility of soils might be expected to be related to the magnetite content of parent rocks. However, magnetite is more resistant to weathering than other ...
