Competing Diffusion Pathways in High-Temperature Metamorphic Quartz
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 ...
The Distribution of Hydrous Impurities in Quartz : The Role of Twinning
Quartz crystals have been studied since ancient times by scientists and natural philosophers attempting to unlock the mysteries behind their aesthetic appearance and cryptic morphological properties. Previous studies ...
Rhombohedral vs. Prism Sector Zones in Hydrothermal Quartz Crystals : Implications for Growth Dynamics
Gemmy hydrothermal quartz crystals typically exhibit each of their six prism and six rhombohedral crystal faces. However, discerning which of the crystal faces were actively growing at any given time during construction ...
