Fluid flows and RNA-trapping in 2D and 3D Hadean hydrothermal submarine vent models (P09)

我们的目标是揭示在热液喷口烟囱壁上产生的无机膜中浓缩核酸的物理和化学先决条件，这些无机膜在哈迪恩条件下形成于碱性泉水中。我们对3D Hadean喷口模型的初步数据表明，烟囱结构包含微米大小的内部口袋(“微口袋”)，这些口袋可以作为流动通过烟囱的核酸的潜在集中地。我们将结合两个2D喷口模型的实时成像和完全形成的3D喷口的详细结构量化，以约束烟囱微囊中化合物堆积的物理和化学条件。

We aim to uncover the physical and chemical prerequisites for the enrichment of nucleic acids within the inor-ganic membranes produced in the chimney walls of hydrothermal vents, that form in alkaline springs under Ha-dean conditions. Our preliminary data on 3D Hadean vent models indicates that the chimney structure contains micron-sized internal pockets (“micropockets”) that can serve as potential concentration sites for nucleic acids that flow through the chimney. We will combine live imaging of both 2D vent models with detailed structure quantification of fully formed 3D vents to constrain the physical and chemical conditions for compound accumulations in chimney micropockets.
