贵州瓮安陡山沱组磷块岩生物标志物特征及对沉积环境的指示OACSCDCSTPCD
Biomarkers of the phosphorites and their indicators of the sedimentary environments of the Doushantuo Formation in Wengan, Guizhou
贵州瓮安新元古界陡山沱组磷块岩中发现的瓮安生物群主要包括多细胞藻类、蓝菌、疑源类、后生动物休眠卵及胚胎、管状后生动物和两侧对称的后生动物等化石类型.对瓮安陡山沱组磷块岩的有机地球化学分析表明,烃类有机组分包括正构烷烃、萜类、甾类和类异戊二烯烃.正构烷烃主峰为C21,碳数分布范围宽;OEP值为1.03,接近1.Pr/Ph比值为0.95,植烷略显优势.规则甾烷呈不对称的"V"字形分布,表现为C27＞C29＞C28的分布特征.C27占优势可能是由大量的…查看全部>>
The fossil assemblages of the Wengan biotas identified in the phosphorites from the Neoproterozoic Doushantuo Formation in Wengan, Guizhou consist of multicelluar algae, cyanobacteria, Acritarchs, dormant eggs and embryos of metazoas, tabular metazoas and bilateral metazoas and so on. The organic geochemical analysis of the phosphorite samples collected from the Doushantuo Formation in Wengan has disclosed that the hydrocarbon fractions contain n-alkanes,…查看全部>>
