| 摘 要： | <正> 塔里木盆地中新世地层分布广泛,地表露头和钻井揭露所得资料表明,位于天山前和昆仑山前拗陷中为一套厚度达数千米的碎屑沉积。这套地层不仅厚度大、分布广,且与寻找油气矿藏有着直接关系,为本区石油找矿的目的层之一。本文对盆地北缘、西缘和西南缘十七个地点中新世有孔虫化石的鉴定结果作了分析,对中新世有孔虫群的特征及其地质意义进行了讨论。文中所用化石标本大部分由新疆石油局南疆指挥部化验室提供,一部分由笔者和他们共同采集,化石图版由中国地质科学院地质研究所胡昀、杨安国同志扫描照照像，图表由翁惠华同志清绘，在此一并致

| Abstract: | The miocene beds in Tarim Basin are characterized by variegated clasticdeposits comprising mainly sandstone, siltstone, arenaceous mudstone and mu-dstone with intercalations of gypsum and occasionally of conglomeratic beds.The whole sequence is predominated by dark brownish, brownish, reddish andyellowish strata intercalated with subordinate dark grey, grey and greyishgreen beds. Gypsum deposits are better developed in the middle and lowerparts. |
