摘    要:在张录易、李勇(1991)初步研究的基础上,作者再次系统采集化石并研究,进一步查明了陕南晚震旦世高家山生物群中瓶状微化石的产出层位、地理分布、宏观特征和属种组合,计有ProtolagenaZhangetLi,p.gaojiashanensisZhangetLi.P.Papillata(Zhang),P.cylindrata(sp.nov.);Sicylagenaformosa(gen.etsp.nov,),S.latistuma(gen.etsp.nov.)和一未命名的化石。同时借用电子探针能谱分析和激光分子拉曼微探针等设备对壳壁特征和壳壁物质成分做了尝试性研究,取得较好的效果。

关 键 词:陕南  灯影组  瓶状微化石

Abstract:On the vase-shaped microfossils of Gaojiashan biota of Sinian in Southern Shaanxi,the prelimi-nary researh is made by Zhang Luyi & Li Yong(1991).After this,the author has carried out anothercollection and study for the second time. From which,it gains a better understanding of the microfossilsin their shapes and stratigraphical and geographical distribution. According to characteristics of tests,itis estabished that the microfossil assemblage has members including Protolagena limbata Zhang et Li,P. gao jiashanensis Zhang et Li,P,papillata (Zhang),P. cylindrata(sp,nov.);Sicylagena formosa (gen.et sp. nov. ),S. latistoma(gen. et sp,nov.),and an indeterinated form. In addition,the author has yet triedto determine the compositions of test wall of the microfossils with the aids of both electron spectroscopeand Laser Raman molecular microprobe spectrum,and which gives a good effect.
Keywords:Southern shaanxi Dengying Formation Vase-shaped  microfossil
