Speaker Dr. Jason Price Predicts "Solubility Thresholds" this week.

  • Sep 15, 2018

EES' Distinguished Speaker this week is Dr. Jason Price, Associate Professor in Environmental Studies at Illinois College. He will present "Predicting radioactive accessory mineral dissolution during chemical weathering: The radiation dose at the solubility threshold for epidote-group detrital grains from the Yangtze River delta, China."

The epidote-group are calcium-bearing silicate minerals that, if soluble during chemical weathering, are capable of consuming atmospheric CO2 over geologic time.  Epidote-group minerals may host uranium and thorium, and be highly soluble as a result of radiation damage to the crystal structure.  The radiation dose of relatively insoluble epidote-group mineral grains extracted from sediments of the Yangtze River delta, China, were measured.  It was determined that epidote-group minerals are capable of withstanding a radiation dose before becoming soluble that is approximately double that for highly resistant zircon. 

Join us for this in depth look at solubility thresholds in the Yangtze River on Friday, September 21, 2018 at 12:30 PM in Room 204, Natural Science Building on the East Lansing Campus.
