报道产自新疆天山南麓轮台县吐克尔明地区第三系苏维依组的５属１０种介形类化石和２属５种轮藻化石，并讲座其地质时代和上、下第三系的界线。

Only a few fossil ostracods were reported from the Suweiyi Formation of Tarim Basin in the past. The specimens described in the present paper were collected from a Tukermen section in Tarim Basin, which contains nine species of five genera. They are mostly distributed in the upper part of this formation, while a few species from the lower part are associated with charophyte fossils which are rich in quantity but low in diversity.\;According to the occurrence of those ostracod species in other areas of NW China, the Suweiyi Formation might belong to Miocene in age and also probably contains Oligocene deposits due to the presence of the Sphaerochara Charites charophyte assemblage.
