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.

我们的目标是揭示在热液喷口的烟囱壁中产生的无机膜内核酸富集的物理和化学先决条件，该膜形成于Ha-dean条件下的碱性泉中。我们对3D冥古宙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”），可以作为潜在的浓度位点的核酸流过烟囱。我们将结合联合收割机现场成像的二维通风口模型与详细的结构量化完全形成的三维通风口，以限制在烟囱微囊化合物积累的物理和化学条件。
