Two Silurian sections were re-measured, one being situated on the northern bank of the Yinshuihe River and the other on the northern bank of the Shouxinghu Lake of the Lazhuglung area of Doima, Rutog, Tibet. The lower part of the Shouxinghu Formation contain graptolites Spirograptus sp. and chitinozoans Ancyrochitina brevicollis and Conochitina sp., indicating a Llandovery age. Real Ordovician rocks have not been found until now there. The Silurian rocks in that area were divided in ascending order into the Llandovery Yinshuihe and Shouxinghu Formations, the Wenlock Pur Co Formation and the Ludlow-Pridoli Yeniupo Formation, a new lithostratigraphic unit were established, on the basis of diversified faunas.
