9417787安德森提出的研究目的是:(1)开发和测试一种新的方法来评估喷发前的气体含量通过对斑晶和火山渣玻璃中玻璃包裹体的分析,确定了玄武岩岩浆中的CO2(特别是CO2);(2)将该方法应用于基拉韦安苦橄岩和分异熔岩,以限制母体岩浆的整体CO2含量,并量化岩浆储存、运输和喷发过程中的气体损失。 这种方法将允许估计喷发前的气体含量和大量的二氧化碳在许多岩浆,包括那些气体监测数据是不存在的。 对喷发前岩浆气体的可靠估计在概念上对于理解岩浆动力学、火山演化、火山与深成岩之间的关系以及与气候变化和质量变化有关的火山排放物具有重要意义。
英文摘要
9417787 Anderson The aims of the proposed research are: (1) to develop and test a novel approach to assess the pre-eruptive gas content (especially CO2) of basaltic magmas through analysis of glass inclusions in phenocrysts and scoria glasses; (2) to apply the approach to Kilauean picrites and differentiated lavas in order to constrain the bulk CO2 contents of parental magmas, and to quantify gas loss during magma storage, transport, and eruption. This approach will allow estimation of pre-eruptive gas contents and bulk CO2 in many magmas, including ones for which gas monitoring data is non-existent. Reliable estimates of pre-eruptive magmatic gas would be conceptually important for understanding magma dynamics, volcano evolution, relations between volcanoes and plutons, and volcanic emissions relevant to climate change and mass extinctions.
