9418157 Rutherford该项目继续进行旨在了解钙碱性岩浆系统中的条件和岩浆过程的实验工作。 本研究的总体目标是更好地了解这些岩浆的演化,以及对它们的脱气,混合,在地壳岩浆房中的定位和喷发的控制。 这些目标将通过确定与固定或可测量组成的C-O-H-(+ S + Cl)流体平衡的Al-Algges晶体熔体平衡来实现。 同样感兴趣的是各种C-O-H-S物种在熔体中的溶解度测量,并建立状态方程,描述流体相逸度与P,T和组成的变化。
英文摘要
9418157 Rutherford This project continues experimental work directed at understanding conditions and magmatic processes in calc-alkaline magma systems. The overall objective of this research is to better understand the evolution of these magmas, and the controls on their degassing, mixing, emplacement in crustal magam chambers, and eruption. These objectives will be achieved by determining crystal melt equilibria for assembalgges in equilibrium with a C-O-H- (+ S + Cl) fluid of fixed or measureable compositions. Of equal interest are solubility measurements of the various C-O-H-S species in melts, and establishment of equations of state which describe changes in fluid phase fugacities with P, T, and composition.
