Quantative Studies of Submarine Lava Flow Morphology

本研究将开发基于海底熔岩流表面形态和纹理的方法，利用实验室模拟、建模和海底流动制图来推断海底熔岩流的就位条件。实验室实验将在冷蔗糖罐中使用聚乙二醇来模拟硅酸盐熔岩。疏浚样本将被用来从它们的晶体含量和流变性能来估计水流的喷发速率。结果将最终导致脊演化的约束模式。

This study will develop methods for inferring the emplacement conditions of submarine lava flows based on their surface morphology and texture, using laboratory simulations, modeling and mapping of undersea flows. Laboratory experiments will use polyethylene glycol in tanks of cold sucrose to simulate silicate lavas. Dredge samples will be used to estimate eruption rates of flows from their crystal content and rheological properties. The results will ultimately lead to constraining models of ridge evolution.
