Emplacement of Silicic Lava Flows and Domes

这个项目是模拟几个不同方面的 熔岩流和圆顶的就位， 实地测绘，同位素测定，实验室模拟， 地形和遥感数据集的图像处理，以及 冷却的理论分析 目的：（1）确定 火山岩结构、挥发分含量、同位素组成之间的关系 特征和喷发参数;（2）使用热红外- 红色光谱法绘制熔岩流的化学成分;（3）地图 成分变化和计算冷却剖面的一个非常 爱达荷州西南部大型流纹岩流;（4）使用实验室和 理论模型，以确定哪些因素控制 半球形的侵入式或突出式。

This project is to model several different aspects of the emplacement of silicic lava flows and domes, using a combination of field mapping, isotopic determinations, laboratory simulation, image processing of topographic and remote sensing data sets, and theoretical analyses of cooling. Aims: (1) determine relationships among lava texture, volatile contents, isotopic characteristics, and eruptive parameters; (2) use thermal infra- red spectrometry to map the chemistry of lava flows; (3) map compositional variations and calculate cooling profiles of a very large rhyolite flow in SW Idaho; (4) use laboratory and theoretical models to determine which factors control the intrusive or extrusive style of silicic domes.
