| 摘 要： | 本文利用电子探针微区分析技术(EPMA),首次分析了采自贵州瓮安北斗山磷矿区陡山沱组外壁呈瘤状及多边形板片状的磷酸盐化球状化石的元素地球化学含量,包括常量元素氧化物含量和部分稀土元素含量,经初步对比发现:具瘤状及板片状外壁的两类球状化石,由内至外常量元素含量的变化趋势大体相似,表明归人同一生物大门类的可能性较大;与磷块...

| Abstract: | The Ediacaran Doushantuo Formation in Weng'an and Fuquan areas of the Guizhou Province in southern China hosts high-grade phosphorus ore deposits and exceptionally well-preserved phosphatic microfossils that are commonly less than 1 mm in diameter. Earlier studies attributed these fossils to algae or acritarchs. In the last decade,researchers found that the spherical microfossils,in a large proportion,show metazoan embryonic development features with early cleavage stages. Thus these spherical microfossils ... |
