Volcanic glass has been used extensively as a paleoaltimeter. Deuterium (2H) concentrations in have found to be stable over geologic timescales, making δ2H (also known δD) reliable proxy for ancient water chemistry. However, continued work revolves around better understanding how different factors affect preserved volcanic ash. Here, we analyze δD the Rattlesnake Tuff (RST), widespread ca. 7 Ma ash-flow tuff, and create paleoisoscape assess variations across Oregon during that time. To this...
