- Summary:
- This paper is a classic synthesis of observations on volcanoes with those on intrusive bodies. Daly's interpretations applied to Hawaii from only part of the paper, but these interpretations are strongly influenced by his observations made elsewhere in the world. Daly discusses Kilauea with regard to continuity of activity at central vents, which he believes to be due partly to exothermic reaction in the magma column, and partly to the continued supply of magma from depth by two-phase convection. Two-phase convection is defined as a continuous displacement of heavier, gas-free magma at the top of the magma column by new, gas-charged, vesiculating magma from depth. Daly makes a critical summary of the heat balances and gas evolution in magmatic system. He calculates heat loss by conduction and by radiation from the lava lake surface.
