Concord EPMA_Glass_METHOD_2.0

Analytical method description file: This method was designed primarily for analysis of volcanic glasses (e.g. tephra and obsidians) by EPMA (electron probe microanalysis) using the ARL-SEMQ electron microprobe at Concord University. This descriptor utilizes the tephra community EPMA-SEM method template, an implementation of the Community-based Recommendations on Collection, Analysis and Correlation of Tephra Data.
