International Research Fellowship Program: Quantification of Lava Flow Emplacement Processes Using Experimental Petrology and Multiphase Flow Dynamics

0204064蒂斯代尔国际研究奖学金计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了联合研究的机会，以及使用独特或互补的设施，专业知识和国外的实验条件。这个奖项将支持20-Rachel Teasdale博士与英国布里斯托大学的Steve Sparks博士合作进行为期四个月的研究。该项目的目的是量化玄武岩熔岩流的堆积，以增加对条件的了解发生在喷发前和运输过程中。 PI将测量来自非充气海底熔岩流和实验产生的可变挥发性含量熔岩的高挥发性含量岩浆的堆积度;将从脱气实验收集的结晶度数据与在大气压冷却实验中在开放流道中发展的堆积度结合，联合收割机将开发一个形态-结晶度行为的模拟流动模型。 该项目通过建模和观察来确定熔岩流行为的特征，将对公共安全问题产生影响。Sparks博士是火山流研究的领导者，并在熔岩流结晶领域拥有专业知识。

0204064TeasdaleThe International Research Fellowship Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will support a twenty-four month research fellowship by Dr. Rachel Teasdale to work with Dr. Steve Sparks at the University of Bristol in the United Kingdom.The purpose of this project is to quantify the crystallinities of basaltic lava flows to increase understanding the conditions that occur prior to eruption and during transport. The PI will measure crystallinities from magmas with high volatile content from non-gassed submarine lava flows and experimentally produced lavas at variable volatile content; combine crystallinity data collected from degassing experiments with crystallinities that develop in the open flow channel at atmosphere pressure cooling experiments and she will develop an analog flow model for morphology-crystallinity behavior. This project, with its modeling and observations to determine the characteristics of lava flow behavior, will have an impact on public safety issues.Dr. Sparks is a leader in the study of volcanic flows and has expertise in the area of crystallization of lava flows.
