| Abstract: | The authors have made detailed study and division on Silurian strata in the Xainza area,north-ern Tibet,determined the Silurian lithostratigraphic and biostratigraphic units and established the biostrati-graphic sequence.A four-fold division has been proposed for the first time and concrete opinions have been put forward for the determination of the location of the boundary between the Ordovician and Sil-urian.This provides an important basis for the study and division of the Silurian in Tibet and throughout China. |
