| Abstract: | Chert layer occurs in Motuosarla iron deposit and contain some hot water deposited minerals.Analysis of the chert show high concentmtion of Fe 2O 3,Au,Ag,Cu,Pb,Zh,Sb and Hg and low concentration of Cr,Ni,Co,FeO,Al 2O 3 and Al/(Al+Mn+Fe) is low.In the genetic discrimination plot major and trace elements of the chert all fall into or near the field of hot water sedimentary rocks.REE and O,Si isotope analysis are characterized by hot water sedimentation.All the data indicate that the chert layer is formed by hot water sedimentation. |
