摘　　要：塔里木盆地北部石炭纪孢子花粉非常丰富，属种众多，保存完美，经研究共计有７４属，２３１种。根据孢子花粉演化及其在地层中的分布规律，自上而下划分出９个孢子带：９Ｐｒｏｐｒｉｓｐｏｒｉｔｅｓｌａｅｖｉｇａｔｕｓ－Ｇｒｕｍｏｓｉｓｐｏｒｉｔｅｓｖａｒｉｏｒｅｔｉｃｕｌａｔｕｓ（ＬＶ）带８Ｂｅｌｉｓｐｏｒｉｔｅｓｎｉｔｉｄｕｓ－Ｍｕｒｏｓｐｏｒａｃａｎｄｉｐｌｉｃａｔａ（ＮＣ）带７Ｒａｉｓｔｒｉｃｋｉａｎｉｇｒａ－Ｓｃｈｕｌｚｏｓｐｏｒａｃａｍｐｙｌｏｐｔｅｒａ（ＮＣ）带６Ｌｙｃｏｓｐｏｒａｐｕｓｉｌａ（ＰＵ）带５Ｓｃｈｏｐｆｉｔｅｓｃｌａｖｉｇｅｒ－Ａｕｒｏｒａｓｐｏｒａｍａｃｒａ（ＣＭ）带４Ｓｐｅｌａｅｏｔｒｉｌｅｔｅｓｐｒｅｔｉｏｓｕｓ－Ｒａｉｓｔｒｉｃｋｉａｃｌａｖａｔａ（ＰＣ）带３Ｓｐｅｌａｅｏｔｒｉｌｅｔｅｓｂａｌｔｅａｔｕｓ－Ｒｕｇｏｓｐｏｒａｐｏｌｙｐｔｙｃｈａ（ＢＰ）带２Ｋｒａｅｕｓｅｌｉｓｐｏｒｉｔｅｓｈｉｂｅｒｎｉｃｕｓ－Ｕｍｂｏｎａｔｉｓｐｏｒｉｔｅｓｄｉｓｔｉｎｃｔｕｓ（ＨＤ）带１Ｖａｌａｔｉｓｐｏｒｉｔｅｓｖｅｒｕｃｏｓｕｓ－Ｒｅｔｕｓｏｔｒｉｌｅｔｅｓｉｎｃｏｈａｔｕｓ?Diverse and well preserved palynofloras are found in the cores drilled from Northern Tarim basin,Xinjiang,China.Miospores are particularly abundant,acitarchs and scolecodonts occur interquently. As a result of extensive research on miospore assemblages from the cores of the Northern Tarim basin,the sequence has been subdivided into nine miospore zonations,with eight zones in the Lower Carboniferous and one in the Upper Carboniferous,as listed below in order from youngest to oldest: 9 Proprisporites laevigatus-Grumossisporites varioreticulatus (LV)zone 8 Bellispores nitidus-Murospora candiplicata (NC)zone 7 Raistrickia nigra-Schulzospora campyptera (NC)zone 6 Lycospora pusilla (PU)zone 5 Schopfites claviger-Auroraspora macra (CM)zone 4 Spelaeotriletes pretiosus-Raistrickia clavita (PC)zone 3 Spelaeotriletes balteatus-Rugospora polyptycha (BP)zone 2 Kraeuselisporites hibernicus-Umbonatisporites distinctus (HD)zone 1 Vallatisporites verrucosus-Retusotriletes incohatus (VI)zone The Miospore Zonations of the Carboniferous in the Northern Tarim basin,Xinjigang,may be correlated with those of China,West Europe,and Northern America.
