文摘
- •
Water greatly affects the electrical conductivity of andesitic melt.
- •
Water-rich andesite explains the conductive bodies in the mid crust of subduction arcs.
- •
Hydrous magmas pond at water saturation pressure.
- •
Super-hydrous magmas may not be local anomalies but seem to define the rule.
