Paleomagnetism of cored sediment from Lake Atitlán, Guatemala: a preliminary study

Clay and silt in a 4-meter piston core from the deep basin of Lake Atitlan possess a strong and stable remanent magnetization when subjected to alternating-field demagnetization. We used paired samples from 263.5 centimeters and eight closely spaced samples between 276.4 and 282. 7 centimeters to as...

Con objeto de evaluar las propiedades de los sedimentos en estudios de variación secular, se utilizó un par de muestras de la profundidad de 263.5 cm y ocho muestras espaciadas entre los 276.4 y 282. 7 cm. La inclinación media determinada en este estudio es de 25.9°, la cual es cercana a la inclinación dipolar axial (27. 7°) para el lugar. El portador de la magnetización remanente en los sedimentos es probablemente magnetita.Universidad Nacional Autónoma de México.
