唐烽[1]1997年在《华北地台东缘晚前寒武纪地层及宏体化石研究》文中研究表明This thesis is resulted from the synthetical studies of the LatePrecambrian strata and megafossils in eastern margin of the North ChinaPlatform(including southern Eastern Liaoning Peninsula, Northern Anhuiand Jiangsu Provinces). The author has reinterpreted the geologicalrecords such as sequences and sedimentary environments of the strata, megafossils, geochemical data, paleogeomagnetic materials,chronostratigraphic and biostratigraphic data and made the firstmicroscopic observation of the megafossils from the Late Precambrianstrata under a fluoromicroscope.The succession of various lithostratigraphic formations of the Neo-proterozoic strata in the south Liaoning Province and Xuzhou-Huainanarea has been confirmed and revised after paying particular attention tothe field markers of outcrop sequence stratigraphy and megafossilsdistribution. A new scheme of biostratigraphic correlation has beenproposed from the view-point of the four evolution stage of themegafossils (including macroscopic algae, paramedusoid, vermes) subdividedas follows: (1) Liulaobei-Diaoyutai and Nanfen-Luotuoling period withthe character of some large macroscopic algae fossils; (2) Jiuliqiao-Changlingzi and Nanguanling peroid flourishing various vermes fossilsaccompanied by some macroscopic algae fossils; (3) Jiudingshan, Zhangquand Weiji-Yinchengzi, Shisanlitai and Majiatun period emerging a largenumber of macroscopic algae fossils distributed in the thin blackcarbonic rocks mostly belongs to CS sector after transgressive systemstract; (4) Wangshan-Xingmingcun period with enormous paramedusoidmetazoans in Xingmingcun Formation floating on sea basin far away fromoffshore.By means of analysing the microscopic characteristic of themegafossils under transmissive-light and fluorescent-light microscopes,the author has proposed some ideas explained as follows: (1) themegafossils of Late Precambrian in this area were almost multicellularorganism fossils; (2) a portion of the chuaria fossils might group tovolvox algae of green alga because of the characteristic of tiny ballsimilar to multicellular feature; (3) the thin sections of themacroscopic algae fossils show small polygon net shape mostly similar tothe pseudofilm character of brown alga; (4) worms and paramedusoidssections appear some approaching circle morph of cellular level might bemulticellular morph of the metazoans.
唐烽, 尹崇玉, 王自强, 陈孟莪, 高林志[2]2005年在《华北地台东缘新元古代地层对比和宏体化石研究的进展和发展趋势》文中提出尽管利用多重地层学方法,对华北地台东缘新元古代地层的划分和对比研究取得了很大的进展,但仍然存在很多争议和问题。今后应在以下几方面展开研究:①寻找新元古代Rodinia超大陆热构造事件和冰川事件的地层学标志,厘定这些标志在地层柱中的位置及其与宏体化石演化阶段的对应关系;②结合碳酸盐岩中C、O和Sr同位素地层学研究,寻找和鉴别新元古代地层中的火山岩和火山碎屑岩,测定其中锆石的U-Pb年龄,解决与华南地区新元古代年代地层的对比问题;③划分“辽南生物群”和“淮南生物群”的不同生物组合,明确各组合的演化历程,深入探讨其谱系归属及与华南地区晚新元古代生物群的关系,完善华北地台东缘新元古代生物地层划分和对比的方案。
