| Abstract: | The magnetic remanence of the andesitic pumice of the Nevado del Ruiz 1985 eruption has the multi-component nature. The major normal component behavior is due to the titanomagnetite phase with variable chemistry. The major reverse component has a peak demagnetization and acquisition range between 200°-225℃ but no such mineral phase could be detected. The titanomagentite phase contributes to the major normal component and has probably no relation to the reverse magnetization. |
