小行星或彗星与行星表面的碰撞所产生的冲击熔片的矿物学和岩石学是冲击火山口组中的一个主要关注领域。我们有兴趣了解过热，同化过程，分馏过程以及与目标地质的链接，并将其作为融化过程的源岩。另外，通过现场研究和实验室实验对摩擦熔化进行了广泛的研究。与矿化类型密切相关的海底长英质岩浆系统，从源肥力，沉积和结晶动力学以及相关的分馏和挥发性相析出方面进行了研究。
The mineralogy and petrology of impact melt sheets generated by the collision of asteroids or comets with planetary surfaces is a major area of interest within the impact cratering group. We are interested in understanding superheating, assimilation processes, fractionation and links to target geology as source rocks for the melting process. In addition, frictional melting is studied extensively, via both field studies and laboratory experiments. Hypabyssal felsic magmatic systems closely related to various types of mineralization are examined in terms of source fertility, emplacement and crystallization dynamics, as well as related fractionation and volatile phase exsolution.
