学术兴趣:
I am primarily interested in constraining the processes that govern the evolution, differentiation and stratification of continental crust through petrographic (studying minerals and whole-rock compositions) and experimental studies of volcanics related 到俯冲和伸展.
内容:
As an outdoor enthusiast and geologist, I enjoy discovering how the combined effects of tectonics and magmatism lead to the production of continents and fabulous landscapes 在美国. My research on the origin and evolution of continental crust (silica-rich, buoyant sections of 地球’s crust) incorporates both field and experimental work, with several field sites in the western US, Caribbean and the Aleutians. 我目前 have an active undergraduate research group examining compositions, the mineral phases, 和爆发前的条件(i.e.(温度、压力和溶解挥发性含量) 俄勒冈州南姐妹火山喷发出的火山. 我目前有国家科学基金会的资助 for a suite of experiments on alkaline magmas to develop a calibration for a new hygrometer 基于碱液交换反应的模型. 如果你感兴趣,请发邮件给我 加入我的研究项目.

活动项目
透长石湿度计
我的研究生, Magdalen Grismer and I, are currently conducting experiments that equilibrate sanidine (a K-rich mineral) and a variety of melt compositions to create a suite of experiments that can be used 校正湿度计. 湿度计将能够估算出喷发前的温度 H2O contents for a variety of melt compositions based on pre-eruptive temperature, sanidine 组合物和熔体组合物. 这些实验是在低压条件下进行的 MSEC135西侧的仪器. 我们现在有18个实验要增加 校准. 我们发现,让我懊恼的是,过碱性的熔体会产生 single crystalline composition (±5 mol% orthoclase) and our model design will only 适用于铝质、过铝熔体. 我们希望释放湿度计 模型很快!
Pre-eruptive conditions of Valles Grande Rhyolites, Valles Caldera NM
Magdalen Grismer is interested in understanding the origin and formation of silicic melts in resurgent 火山口系统. Mags is documenting the petrology and pre-eruptive storage conditions of the domes, experimentally testing those storage conditions, and, finally, addresses 苯胺结晶动力学. 我们已经确定了卤素浓度 as signaling infiltration of reduced fluids that have the fundamental potential to change the petrology and major element chemistry of the Valles Magmatic system.
科努达斯山脉稀土元素生存力
我的学生, 高管梅森Woodard, is currently using petrologic methods to determine temperature-pressure conditions of intrusive bodies in the Cornudas Mountains that are associated with REE deposits. The project is in collaboration with Ginger Macklemore and Nels Iverson in the Bureau 地质. 梅森 is collecting mineral compositions, whole rock compositions and sample petrology and using model thermometers and barometers from the literature to 确定它们的侵入温度、压力和流体含量.
Molecular complexation of rare earth elements (REE) in high temperature and pressure 超临界地质流体(美国能源部资助项目)
This project aims to generate a comprehensive set of solubility measurements of Rare 地球 Element (REE)-bearing phosphates using synthetic REE end-member crystals, which will be equilibrated with a variety of neutral and acidic solutions between 500 – 700°C,压力0.5 ~ 2kb,用于冷密封压力容器. Banerjee Debarati is one of three PHD students, working to understand REE solubility in hydrothermal fluids at high temperature (>500°C). 该项目是美国能源部合作资助项目的一部分 铅的 Dr. 亚历克斯Gysi 在与 Dr. 妮可Hurtig 在核磁测井仪. Project work will be collaborative between NMT, Los Alamos and University 印第安纳州.
