Bishop tuff是什么
Webals designed to mitigate matrix effects and analytical artifacts. Bishop Tuff inclusions are unmodified by magmatic degassing, diffusive loss, or assimilation-fractional crystallization processes. The hydrogen isotope composition of the rhyolitic Bishop Tuff is most comparable to basaltic glass inclusions from subduction zones worldwide. Web(a) and (b) highlight the influence of alteration, especially for biotite from the eastern Bishop Tuff. For comparison, the data of Hildreth (1979) are plotted as grey diamonds.
