Abstract

Abstract

Geochemically,radiolarian cherts samples from Nanm in shui Formation in middle section of Kelamaili show two distinct types of geochemist ries.One type of samples features midocean-deep sea sedimental element association:the values of Al₂O₃/(Al₂O₃+Fe₂O₃)from 0.11 to 0.19(<0.4),low ΣREE(6.34×10^-6～26.37×10^-6),low LaN/YbN(0.02～0.16),and the values of Ce/Ce^* from 0.002 to 0.08,LaN CeNfrom 1.29 to 1.97.
