| 中文摘要: |
We got two cores from 10 miles east of Zhoushan islands about 29 m in water depth in 1979 and 1980.DC1 core, 26 m long, can be divided into two layers; 0-19.4 m, brown-yellow, silty-clay, rich in foraminifera, 19.3-26 m, grey silt. DC1 core, 91 m long, 7 miles south of DC1 core. The colour for 0-16.6 m is the same as for 0-19.4 m of DC2 core, brown silty-clay, rich in foraminifera too. The results of paleomagnetic measurements show:there are 464 specimens in DC1 and DC2 cores altogether; AF demagnetization often shows that 95% of all the specimens belong to normal polarity epoch, and the others are reversal ones.
We consider that more stranger intensity may represent the warming period and transgression period, and vice versa. At least DC, and DC2 cores provide such an evidence for this. It is obvious that glacial period should be low peak period of intensity, and interglacial period should be its high peak period. |
