9614229 McMillan This research proposes to develop and calibrate a new method of volatile analysis based on infrared reflectance spectroscopy, which will only require singly polished samples, and which does not rely on measurement of sample thickness for concentration determination. Preliminary results show that the technique will work for CO3 and H2O species in the concentration range above ~0.1-0.5 wt% for basaltic compositions, and encouraging results have been obtained for CO2 dissolved in rhyolite at the 500-2000 ppm level. These fundamental spectroscopic studies will be applied to several suites of samples. The results will be useful to workers in the fields of geochemistry and volcanology.

9614229 McMillan本研究提出开发和校准一种基于红外反射光谱的挥发物分析新方法，该方法仅需要单独抛光的样品，并且不依赖于测量样品厚度来确定浓度。 初步结果表明，该技术将工作的CO 3和H2O物种的浓度范围以上~0.1- 0.5wt%的玄武岩成分，并已获得令人鼓舞的结果，在流纹岩中溶解的CO2在500-2000 ppm的水平。 这些基本的光谱研究将应用于几套样品。 研究结果对地球化学和火山学工作者有一定的参考价值。
