摘要:

根据我国第三纪有孔虫的成分、性质及其丰度最高属种的相似性、差异性、特有属种的分布等,可合理地将它们分成六个动物群,圆盘虫(Discorbis)动物群、货币虫(Nummulites)动物群,面包虫(Cibicides)动物群,圆球虫-中垩虫(Orbulina-Mio-gypsina)动物群,卷转虫(Ammonia)动物群,普林虫-星轮虫(Pulleniatina-Asterorotoa-lia)动物群(图1)。前三个动物群属早第三纪,后三个属晚第三纪。

Abstract:

Based on their compositions and characteristics as well as resemblanceand difference between the most abundent genera and spicies,six foramini-feral faunas are recognized,namely:1.the Discorbis fauna,2.the Nummu-lites fauna,3.the Cibicides fauna,4.the Orbulina-Miogypsina fauna,5.the Ammonia fauna and 6.the Pulleniatina-Asterorotalia fauna.The firstthree of them belong to the early Tertiary while the last three to the late Tertiary.The Discorbis fauna are mainly found in many places of East China,suchas the Bohai gulf,the Jianghan basin,the north part of Jiangsu province,the Sanshui basin,etc.The Ammonia fauna are mainly reported from the W.Tarim basin.As they may tolerate some lowering of salinity,they serveas important facial indicators in searching for oil and gas reservior of brackish-water origin.The Cibicides fauna and the Orbulina-Miogypsina faunacomprising entirely shallow marine and pelagic genera play an improtant rolein prospecting for oil and gas reservior of epeiric origin.The Cibicides faunais discovered from the S.W.border of Tarim,while the Orbulina-Miogy-psina fauna has much wider distribution in Taiwan province and the Leiqiong region of Guangdong province,and on the continental shelf of the South and East China Seas.
