An Experimental Study of Coupling between Stress-Driven and Reaction-Driven Melt Migration in Mantle Rocks

火山活动是形成和塑造地球表面的几个重要过程之一。融化物是由像皮纳图博火山或圣海伦火山这样的火山喷发出来的，也来自大洋中山脊的巨大系统。地表喷发的熔岩已知源自地球？地幔是部分熔融的，即大部分固体岩石中的一小部分熔融，但人们对熔融如何穿过宿主固体知之甚少。熔体被认为是由应力（压力）和化学反应驱动的，本实验研究的目的是研究这两个过程如何相互作用，以在高温高压下引导和运输熔体。除了有助于我们对基本过程的理解之外，本研究的更广泛影响包括为本科生提供研究经验，为研究生提供培训，以及开发新的实验技术

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
