説明
Measurements of remanent magnetizations of juvenile and lithic fragments and their matrix in a pyroclastic (tuffite) dike in central Kii peninsula, SW Japan to infer their behaviors at the time of emplacement resulted in average paleomagnetic directions of the declination, inclination, and α_<95> angles were -1.5°, 56.3°, and 8.6°, respectively. In addition, most of measured samples, including juvenile and lithic fragments and matrix, show that their remanent magnetic intensities decrease in temperature range over 250°to 400℃ and magnetic directions become unstable. These results indicate a possibility that at higher temperature fragments and matrix were moving not to get stable remanent magnetization, and then they were cooled down to 300℃ when reached to the sampling point.
