Description
Lucas M Lino and eight co-authors rethink how crystal poor, silica rich magmas form before giant caldera eruptions. The standard story extracts melt from a still, half solid mush of crystals, yet the leftover crystal piles are hard to find. Their 2026 study of the Campo Alegre-Corupá system in Brazil joins crystal textures with thermodynamic modeling to build a dynamic version.
Rocks called syenites turn out to be the missing leftovers, formed when melt was pulled away at low crystal shares, as low as 16 to 33 percent. Rising melt sorted feldspar crystals by size, clumps sank and repacked, and fresh magma recharged the system. That flow driven sorting separated crystals from melt far earlier than still models allow. The result explains how huge volumes of eruptible magma gather in the upper crust.
