Popis:	We report on a detailed investigation of the magnetic properties of tertiary tephra as a function of temperature and magnetic field, over a wide temperature. The tertiary tephra were chosen from two marine sites in the South Indian Ocean. The measurements were made using the electron spin resonance (ESR) technique in the temperature range 4–1100 K and a SQUID magnetometer at temperatures from 4 to 300 K. We show that the magnetic properties of the studied ashes are mainly due to two contributions, a ferrimagnetic one and a paramagnetic one. At moderate magnetic fields, B T
