内容記述(抄録等)During the summer of 1964, seventeen of the rock samples were taken from the so-called intermixing zone (Asami 1957) of the normal and reverse natural remanent magnetization (nrm) at Kawajiri-Misaki (Gape Kawajiri), northern seaside of Yamaguchi Prefecture, west Japan. Only the data on some magnetic properties of these samples; obtained by the direction-measurement of the nrm, by the ac demagnetization experiment, by the thermo magnetic study are given. The direction of the nrm of these rock samples was determined by means of an astatic magnetometer. At first the measurement was made on a fist sized sample originally taken, secondarily the fist sized original rock sample was cut into eight specimens in general. These specimens thus cut were also submitted to an astatic magnetometer in order to the determine the direction of the nrm. The normally and reversely magnetized specimens appeared in about equal numbers. In figure 1, the directions of those nrms are plotted on the stereographic projection. Solid circle indicates that the dip of the nrm of the specimen is downward and open one shows upwards. Symbole 〓 shows the direction of the present geomagnetic field and 〓 is the antipodal (in figures 2, 3, and 5, the same symboles are used). Generally speaking, the specimens had nrms in the directions concentrated well around the direction of the nrm of their mother sample. However, two in seventeen samples had some odd characteristics in the directions of the nrms of each divided specimens. Of the sample, no. KW 64-1509, two specimens show normal nrm and remainders; six specimens were reversely magnetized in situ to the directions of the present geomagnetic field. On the other hand, the sample, no. KW 64-
