项目摘要

Volcanism is one of several important processes that form and shape the surface of the Earth. Melts that are erupted from explosive volcanoes such as Pinatubo or Mt Saint Helens, and from the vast system of mid-ocean ridges. Lavas erupted at the surface are known to originate from the Earth?s mantle as partial melts, i.e., small fractions of melt in mostly solid rock, but how melts move through the host solid is poorly understood. Melts are thought to be driven by both stress (pressure) and chemical reactions, and this experimental study has the aim of investigating how these two processes interact to channelize and transport melts at high temperatures and pressures. In addition to contributing to our understanding of fundamental processes, broader impacts of this study include research experience for undergraduates, training for a graduate student, and development of new experimental techniques
火山作用是形成和塑造地球表面的几个重要过程之一。从皮纳图博或圣海伦斯山等爆发性火山以及大洋中脊的巨大系统中喷发出来的熔体。在地表喷发的熔岩是来自地球吗?的地幔部分熔融,即,在大多数固体岩石中的小部分熔体,但熔体如何通过主体固体移动的了解甚少。熔体被认为是由应力(压力)和化学反应驱动的,这项实验研究的目的是研究这两个过程如何相互作用,在高温高压下通道化和运输熔体。除了有助于我们对基本过程的理解外,本研究的更广泛影响还包括本科生的研究经验,研究生的培训以及新实验技术的开发
