| Abstract: | Bivalve of Paleogene at southwestern margin of Tarim Basin are divided into five assemblages which are: 1. Corbula of Aertashi Formation; 2. Chlamys ( Ae-quipecten) tenuicostatus-Ostrea (Solidoslrea ) hemiglobosa assemblage of Qimugen Formation; 3. Ostrea (turkostrea ) turkestanensis assemblage of Kalataer Formation; 4. Fatina-Liostrea (Kokanostrea ) assemblage of Wulagen Formation; and 5 Ostrea ( Platygena ) asiatic-Amphidonta ferganensis assemblage of Bashibulake Formation. These assemblages correspond respectively with those of Bukhara Formation,SuZak Formation, Alai Formation, Turkestan Formation and Lishitan-Sumusal Formation of middle Asia in USSR.
Ostrea ( Turkostrea ) stritiplicata is different from O. (T. ) turkestanensis Disappearance of.O. (T. )turkestanensis are not followed by appearance of Fatina. First appearance of Fafina comes from middle-upper Kalataer Formation, whose bottom is not equivalent to that of Wulagen Formation, so the position of first appearance of Fatina can not be regarded as bottom of Wulagen Formation. |
