| 摘 要： | 对四川广元上寺上二叠统剖面进行岩石学和地球化学分析,并利用Al/Ti值评估古生产力,而利用Mo、u、V、Cr、V/Cr和V/(V+Ni)来评估沉积环境,进而探讨烃源岩中有机质的积累与海洋初级生产力、沉积环境(氧化还原条件)以及沉积速率之间的关系.研究发现,在大隆组中部,TOC、过剩铝、Cu、Ni和Cd出现高值(TOC平...

| Abstract: | Geochemical and petrological analyses of the Permian section in Guangyuan of northeastern Sichuan suggest that multiple factors influenced the accumulation of organic matter.In this study,we conduct a comprehensive investigation on the geochemistry of the middle part of Dalong Formation to explore the link of accumulation of organic matter to the marine primary productivity,sedimentary environment(oxidation-reduction conditions)and sedimentary rate respectively.We found that high values of Mo,U,V,Cr,as well... |
