Infrared Spectroscopy of Quartz and Feldspar in Alpine Hydrothermal Veins
(2016-10-21)
With the aim of discerning fluid conditions present during
hydrothermal activity associated with Alpine metamorphism, we present new results on the abundance and distribution of hydrous impurities in co-crystallizing ...
Schematic Illustrations of Evolving Tholeiitic and Calc-Alkaline Magmatic Systems: New Models
(2016-10-21)
The dramatic contrast in the geochemical evolution of tholeiitic and calc-alkaline magmatic systems has remained an enigma since their original characterization nearly a century ago. Recently, two new models that describe ...
Competing Diffusion Pathways in High-Temperature Metamorphic Quartz
(2018-03-05)
We present spectroscopic analyses that characterize the distribution and abundance of hydroxyl-bearing impurities within a single quartz crystal grown in hydrothermal fluid. We focus on a gemmy quartz crystal collected in ...
