Extended Data Fig. 4: Selected major-element diagrams showing the geochemistry of quartz-hosted homogenized melt inclusions from the Buck Ridge Volcanic Complex (BRVC).
From: Earth’s earliest granitoids are crystal-rich magma reservoirs tapped by silicic eruptions
The compositions of the BRVC melt inclusions investigated in this study match those of high-silica rhyolitic glasses and melt inclusions from modern ignimbrites (as compiled by ref. 51 – see their work for the complete list of references). Some of the data from Agangi et al. (ref. 25) depart from those compositions along trends projected from pure quartz, likely indicating the incomplete homogenization of the host in their experiments (see Methods).
