[HTML][HTML] What lies beneath? Reconstructing the primitive magmas fueling voluminous silicic volcanism using olivine-hosted melt inclusions
Understanding the origins of the mantle melts that drive voluminous silicic volcanism is
challenging because primitive magmas are generally trapped at depth. The central Taupō …
