An attempt to determine the microwave paleointensity on historic Paricutín volcano lava flows, Central Mexico

We report a preliminary rock-magnetic and microwave paleointensity study of historic lava flows between 1943 and 1948 of Paricutín volcano. These lava flows show well-preserved, well-exposed, fresh and extensive outcrops. Most samples are characterized by simple uni-vectorial plots. The isothermal r...

These lava flows show well-preserved, well-exposed, fresh and extensive outcrops. Most samples are characterized by simple uni-vectorial plots. The isothermal remanent magnetization curves show saturation at low to moderate fields, suggesting titanomagnetite series. From hysteresis experiments magnetic carriers are likely iron-rich titanomagnetites with single-domain or pseudo-single-domain behavior. Microwave paleointensity technique was applied to three selected samples using Kono and Ueno’s (1977) method; i.e., the direction of applied laboratory field was perpendicular to the direction of remanent magnetization. The samples yielded paleointensity values of 11.38, 26.37 and 51.6 microTesla, which are significantly different from expected values. The observed scatter is likely to be caused by the small fraction of natural remanent magnetization used for paleointensity determination, or from not using a cooling rate correction for natural samples.Reportamos un estudio preliminar de magnetismo de rocas y paleointensidad con la técnica de microondas de los flujos de lava históricos entre 1943 y 1948 del volcán Paricutín. Esos flujos de lava muestran afloramientos frescos y bien preservados. La mayoría de las muestras estudiadas se caracterizan por diagramas ortogonales simples. Las curvas de magnetización remanente isotermal muestran saturación en campos bajos a moderados sugiriendo la serie de titanomagnetitas. De los experimentos de histéresis se determinó que los portadores magnéticos son probablemente titanomagnetitas ricas en hierro con un comportamiento de dominio sencillo a pseudosencillo. La técnica de paleointensidad por microondas se aplicó a tres muestras seleccionadas usando el método de Kono y Ueno (1977); i.e., la dirección del campo aplicado en laboratorio fue perpendicular a la dirección de la magnetización remanente. Los resultados de paleointensidad fueron de 11.38, 26.37 y 51.6 microTeslas, que son significantemente diferentes de los valores esperados. La dispersión observada puede deberse a la pequeña fracción de la magnetización remanente natural usada para la determinación de la paleointensidad, o de no haber usado una corrección por la razón de enfriamiento para muestras naturales.Universidad Nacional Autónoma de México.
