Cumulate recycling in igneous systems: the volcanic record
Magmatic evolution creates crystal cumulates. In the current paradigm for the genesis of
evolved magmas, cumulate crystal mushes dominate trans-crustal magma systems that feed …

Most granitoid rocks are cumulates: deductions from hornblende compositions and zircon saturation
Cumulate processes in granitic magma systems are thought by some to be negligible and by
others to be common and widespread. Because most granitic rocks lack obvious evidence of …

Remelting of cumulates as a process for producing chemical zoning in silicic tuffs: A comparison of cool, wet and hot, dry rhyolitic magma systems
We review petrological and geochemical features of silicic pyroclastic deposits of dominantly
low to moderate (0–25%) crystallinity, and volumes in the range of 5–1000 km 3, erupted …
