新疆南天山东部阿尔皮什麦布拉克组的地质时代

GEOLOGIC AGE OF ARPISHMEBULAQ FORMATION IN EASTERN PART OF SOUTH TIANSHAN MOUNTAINS,XINJIANG

通过对标准剖面的两次考察和室内各门类化石鉴定，特别是早泥盆世标准牙形类化石的发现，证实阿尔皮什麦布拉克组的地质时代为洛赫柯夫晚期的ｄｅｌｔａ带和ｐｅｓａｖｉｓ带。

Through the twice field observation of standard section and lab identification of varieties of fossils,especially the discovery of standard condont fossil of Early Devonian,it is confirmed that the geologic age of Arpishmebulaq Formation is delta zone and pesavis zone in late Lochkovian stage.
