The principal investigator will study the interaction between basaltic magma and the crust. In particular, he will investigate the possibility that partial melting of both continental and young mafic rocks as a result of this interaction coupled with subsequent fractionation during ascent, may be the dominant processes whereby evolved rocks are generated and magmatism sustained. This work will utilize properly scaled laboratory experiments, numerical simulations, and linear stability analysis of the onset of convection to help geologists better understand processes responsible for the generation of igneous rocks.

首席研究员将研究玄武岩岩浆与地壳之间的相互作用。特别是，他将调查这种相互作用导致大陆和年轻的镁铁质岩石部分熔融，再加上随后的上升过程中的分馏，这可能是形成演化岩石和维持岩浆作用的主要过程。这项工作将利用适当规模的实验室实验、数值模拟和对流开始时的线性稳定性分析，帮助地质学家更好地了解导致火成岩产生的过程。
