| Abstract: | The 210Pb activity and the heavy metals of Zn,Cr,Cu,Pb,Cd,Co and Ni in corresponding sediment layers in the cores of B3,C2,C4,B6,D4 and D6 from the Jiaozhouwan Bay were measured,and the sedimentation rate and sedimentation environment in different region for the Jiaozhouwan Bay have been discussed.The sedimentation rate had significant difference among the middle,the east coast and the mouth of the Jiaozhouwan Bay with the average between 0.19 cm/a and 3.96 cm/a.According to exactly strata age determined by... |
