Sub project: Experimental constraints on the magnetic mineralogy of Fe-Ti oxides in basalts from HSDP-2 bore hole

Description: Das Projekt "Sub project: Experimental constraints on the magnetic mineralogy of Fe-Ti oxides in basalts from HSDP-2 bore hole" wird vom Umweltbundesamt gefördert und von Universität Heidelberg, Institut für Geowissenschaften durchgeführt. The Hawaiian Scientific Drilling Project (HSDP) provides an excellent opportunity to study the evolution of rock magnetism in relation to the growth history and magmatic evolution of a shield volcano. The main magmatic carriers in the basaltic rocks drilled from the HSDP-2 bore hole are the two Fe-Ti oxide minerals, titanomagnetite and ilmenite. The aim of the present project is to improve the correlations between magnetic properties and chemical-structural characteristics of these oxides at high (magmatic) temperatures, with an emphasis on titanomagnetite. The new data will contribute to a better understanding of rock magnetic properties of subaerial and submarine basaltic rocks that mainly build up the Hawaiian shield In a first stage we plan to determine characteristic magnetic parameters (e.g. Curie or Néel temperature, low-temperature behavior of the magnetic susceptibility, hysteresis parameters at room and low temperature) of synthetic Fe-Ti oxides equilibrated at high temperatures (1000-1150 centigrade), with well-defined compositions (incl. vacancy concentrations) analogous to those in Hawaiian rocks. These new data will be applied especially to submarine samples recovered from the deep part of HSDP-2 that do not show late oxidation features.
