| THE DETERMINATION OF SEDIMENTATION RATE BY 210Pb METHOD |
|
|
| Abstract: |
| The sedimentation rates at East-South part of Jiaozhou Bay and off the Belt of Dingzi Bay was determined with 210Po self-precipitation a spectrum method and 210Po self-precipitation a count method. Three layers are found in the sediment determined, the surface mixing layer, about 0-10 cm, with irregular activity distribution; the middle active decay layer with regular activity; the active background region with uniform activity. The sedimentation rate at East-South part of Jiaozhou Bay is 2.2 mm/year and the sedimentation rate off the delt of Dingzi Bay is 1.8mm/year. |
