摘　　要：中新生代海侵是塔里木盆地地质发展史上的重要事件之一。通过对新近发现的古生物化石和海相地层资料研究,本文提出了早白垩世、晚白垩世、古近纪的海侵范围的新认识。同时,依据露头和钻井资料提出了中新世海水分布的新范围。这些新成果对厘定塔里木盆地中新生代地层时代、建立整个盆地中新生代地层格架和油气远景分析具有重要意义。The cycles of marine transgression and regression during the Mesozoic and Cenozoic are important events in geological history of the Tarim Basin. By studying the marine fossils (foraminifera, nannofossils, marine trace fossils etc. ) found recently in the southwestern and northern parts of the Tarim Basin, this paper presents new knowledge of the distribution of marine transgressions of the Early Cretaceous, Late Cretaceous and Paleogene in this basin. On the basis of foraminiferal fauna Ammonia found in samples from field outcrops and drillholes, the distribution of Miocene marine deposits in the Tarim Basin is suggested. The new progress is of great signif-icance for the division and correlation of the Mesozoic and Cenozoic marine strata, establishment of the marine stratigraphic pattern and evaluation of oil and gas resources in the basin.
