| Abstract: | The article studies the distributive feature of 20 trace elements in surface sediment in thewestern Taiwan Strait, and devides the elements into four combined types according to therelation between elements and sedimentation. 1) The type of adsorption drift (Cu,Zn,Co,Ni, V, B, Li, Cr ); 2 ) The type of advance sedimentation depolymerized (Pb,Sn) ; 3 ) The typeof sedimentation controled primarily by fine sands (Zr, La, Y, Nb,Ti, Ba ); 4)The type of dis-persing sedimentation (Mn, Mo, Sr,Be ).The elemets in the type of sedimentation controled primarily by fine sands have suchfavourable features for mineraltion as high-grade abundance of Zr, high aggregation of con-tent, dishomogenous back-ground parameter and demonstration minerallized by placer.Their distributive area of high aggregation content possesses possibly mineral significance ofsubmarine placer of Zr, Ti. |
