The magnetic studies carried out allowed to determine the presence of detrital magnetite and titanomagnetite, as well as maghemite, pedogenic goethite and superparamagnetic particles (SP). In Verónica soils, a depletion of ferromagnetic minerals is recorded. The dominant process in these soils has been the reductive loss of detrital magnetite ...

Nov 16, 2014· This work presents new rock magnetic results along two loess–paleosol profiles in nearby locations in Argentina. The main objective of this study is to compare the magnetic signals and mineral content of two profiles and determine if the climate during Marine Isotope Stage 5 (MIS 5) and MIS 3 were similar to the present one. The two profiles are located in two different geomorphological ...

MAGNETIC SEPARATION OF THE TITANOMAGNETITE The titanomagnetite ore consists of two main phases: ilmenite (FeO*TiO2) and magnetite (FeO*Fe203) with some ilmenite dissolved in the magnetite matrix. Vanadium is dissolved in the magnetite as V203, thus replacing Fe203. Since magnetite is strongly magnetic compared to ilmenite, the Pipestone Lake ...
