摘要

东帝汶富拉砂岩型剖面的测井和生物地层特征表明其为卡尼—早诺世(Samaropollenites speciosus)带。沉积构造显示浊积岩成因,岩相分析显示火山岩屑颗粒比例较高。孢粉材料呈现出一种可变的保存方式,表明一个复杂的包括长途运输的前埋葬历史。原生植物的存在表明缺氧和缺氧的沉积环境。

The Foura Sandstone type section (Samaropollenites speciosus Zone, Carnian–early Norian; early Late Triassic), Timor-Leste: preliminary correlation between Timor and the Bonaparte Basin
Summary The logging and biostratigraphic characterization of the Foura Sandstone type section, Timor-Leste, show it is Carnian–early Norian (Samaropollenites speciosus Zone). Sedimentary structures indicate a turbidite origin and petrographic analysis reveals a high proportion of volcanic lithic grains. Palynological material presents a variable preservation suggesting a complex pre-burial history involving longdistance transport. The presence of prasinophytes suggests anoxic and euxinic depositional settings.
