Water distribution in a quartz-hosted embayment from the Mesa Falls Tuff
![Photomicrograph showing water distribution in a quartz-hosted embayment, with greater concentrations at the embayment mouth. Includes a plot showing that the temperature in which the water circulated must have been about 500 degrees Celsius.](https://d9-wret.s3.us-west-2.amazonaws.com/assets/palladium/production/s3fs-public/styles/full_width/public/media/images/Figure%202.png?itok=FqU_2NuJ)
Detailed Description
(A) Water distribution in a quartz-hosted embayment measured with synchrotron Fourier Transform Infrared spectroscopy. Warmer colors indicate higher concentrations of water. Dashed line shows a transect of water content that is modeled in panel (B) to indicate that the emplacement temperature of the ash flow deposit must have been about 500 °C (930 °F).
