| Abstract: | The diamond placer in Tancheng county,Shandong province is of a terraced placer from the destroyed occurence of alluvium. In this placer,the grain size of the diamonds which occurs in a alluvial grit gravel of residual two-tarraces are large and more gem diamonds can be selected out. Therefore,this diamond placer can be considered as an important base for gem industry. |
