Acquisition of Externally Heated TZM Pressure Vessel and Diamond Anvil Cell Systems

9910539加德纳基金从这个赠款将使我们能够获得实验设备，以扩大现有的实验岩石学实验室在阿拉斯加大学，费尔班克斯，地质和地球物理系。具体来说，我们将获得一个外部加热的TZM压力容器系统，包括熔炉和加压设备，这将通过将可达到的条件提高到约1250摄氏度，同时包含高达约2000巴的压力，来扩展实验室的现有能力。 这一增加将使我们能够研究玄武岩和安山岩的组成在地壳上部的条件。 建立这一新装置的主要目的是通过提供关于控制和引发火山爆发的过程的宝贵信息，进一步实现阿拉斯加火山观测站的监测目标。 特别是，我们将能够贡献有价值的研究，重点是了解控制爆炸性和喷发性火山活动的过程，如结晶速率，晶体溶解研究，气泡成核和生长，以及使用矿物反应来监测岩浆上升。此外，对气泡成核和生长过程的限制对于理解火山震颤的性质和原因可能非常重要。因此，我们将通过进一步了解控制弧火山作用的过程，为AVO工作增加一个新的维度。*

9910539GardnerFunding from this grant will allow us to obtain experimental equipment to augment the existing experimental petrology laboratory at the University of Alaska, Fairbanks, Department of Geology and Geophysics. Specifically, we will acquire an externally heated TZM pressure vessel system, including furnace and pressurizing equipment, which will extend the current capabilities of the experimental laboratory by increasing the conditions attainable to ~1250 degrees celsius while containing up to ~2000 bars of pressure. This addition will enable us to study basalt and andesite compositions at upper crustal conditions. A primary goal of the establishment of this new apparatus will be to further the monitoring goals of the Alaska Volcano Observatory (AVO) by contributing valuable information on processes that control and initiate eruptions. In particular, we will be able to contribute valuable studies that focus on understanding processes that control explosive and effusive volcanism, such as crystallization rates, crystal dissolution studies, bubble nucleation and growth, and the use of mineral reactions to monitor magma ascent. In addition, constraints on bubble nucleation and growth processes could be very important for understanding the nature and causes of volcanic tremor. Thus, we will be adding a new dimension to the work of AVO by furthering our understanding of the processes that control arc volcanism.***
