Performing experiments in the lab at high-temperatures and pressures allows us to re-create the conditions that occur within the Earth. Comparison of the mineralogy, textures and compositions of natural igneous and metamorphic rocks with those produced in the lab allows us to determine the conditions under which rocks now at the surface formed. However, to achieve this we need reliable high-temperature furnaces that are capable of reproducing, and maintaining for extended periods, naturally occurring conditions. This proposal is for funds to purchase such a furnace. This furnace will facilitate research, and student training, across a broad range of topics. These include: (i) investigating the processes operating within the crust immediately before, and during volcanic eruptions; (ii) determining the conditions within Earth's mantle; (iii) tracking the formation of magmatic ore deposits; and (iv) determining the environmental impact of volcanic degassing.

在高温和高压下进行实验室实验，使我们能够重现地球内部发生的条件。通过对天然火成岩和变质岩的矿物学、结构和成分与实验室产生的岩石进行比较，我们可以确定现在地表岩石形成的条件。然而，要实现这一点，我们需要可靠的高温炉，能够再现并长期保持自然发生的条件。这项提案是为购买这样一个炉子提供资金的。这个熔炉将促进研究和学生培训，涉及范围广泛的主题。这包括：(1)调查火山喷发之前和喷发期间地壳内的活动过程；(2)确定地幔内的条件；(3)追踪岩浆矿床的形成；(4)确定火山脱气对环境的影响。
