Interpreting Stratification in the Sedimentary Record from Experiments on Combined-Flow Red Configurations in a Large Laboratory Flow Duct

最初沉积在浅海水域的古代沉积物显示出独特的分层样式，这被认为是由振荡的风暴引起的流动造成的。对这些矿床及其分层的解释存在争议。PI建议建立一个组合流管道来模拟各种流动环境，并研究在大范围的振荡周期、振荡速度和叠加电流下产生的河床结构和分层。这将促进对古代沉积物和形成它们的水流机制的了解。在大部分实验运行完成后，一个由12位振荡流专家组成的咨询小组同意在麻省理工学院开会一周，检查和讨论结果，并重新设计关键的流动管道运行。他们还将讨论对口译的影响，并计划进一步的工作。

Interpreting Stratification in the Sedimentary Record from Experiments on Combined Flow Bed Configurations in a Large Laboratory Flow Duct Ancient sediments originally deposited in shallow marine waters show distinctive styles of stratification that are thought to be caused from oscillating storm-induced flows. Interpretation of these deposits and their stratification is controversial. The PI proposes to build a combined flow duct to simulate various flow environments, and to study the resulting bedform configurations and stratifications over a wide range of oscillation periods, oscillation velocities, and super-imposed currents. These will then advance the knowledge of ancient deposits and the flow regimes responsible for them. After the bulk of experimental runs are completed, an advisory body of twelve experts on oscillatory flow have agreed to meet at MIT for a week to examine and discuss the results, and remake key flow duct runs. They will also discuss implications for interpretation, and plan further work.
