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...

| Sumario: | 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 assess the sediment for a study of paleomagnetic secular variation. Average inclination of 25.9° is close to the inclination of an axial dipole field (27.7°), and magnetite is the probable carrier of magnetization. |
