新疆准噶尔盆地南缘覆盖区晚白垩世紫泥泉子组介形类动物群
THE LATE CRETACEOUS OSTRACOD FAUNA FROM THE ZINIQUANZI FORMATION IN THE SOUTHERN EDGE OF JUNGGAR BASIN,XINJIANG
【摘要】 在准噶尔盆地南缘覆盖区的紫泥泉子组普遍见到丰富的晚白垩世介形类化石,自西向东面貌一致,分布稳定,计有10属(包括1亚属)17种4比较种2未定种,可归为一个Talicypridea组合,是覆盖区划分和对比紫泥泉子组的重要标志。
【Abstract】 In the southern edge of the Junggar Basin,Xinjiang,abundant Late Cretaceous ostracod fossils have widely been found in the Ziniquanzi Formation which have the same features and distribute steadily from west to east.Within the ostracode fauna,10 genera(including 1 subgenus),17 species,4 species conformis and 2 species indeterminate are identified,which can be classified as one assemblage of Talicypridea.The Talicypridea assemblage is an important index for subdivision and correlation of the Ziniquanzi Formation in this area.
