Magma and Physical Properties of Volcanic Rocks

Abstract

Reasoning about the molten parts in the earth’s crust and upper mantle and various phenomena in magma reservoir requires a knowledge of the way in which the physical properties of molten rocks vary under combined high temperature and high pressure. This paper reports the review of measurements of the velocity and attenuation of longitudinal wave, viscosity, electrical conductivity and the growth velocity of crystals in molten rocks. A conclusion derivable from these measurements is that there is some possibility of the detecting of molten parts in the earth’s crust or mantle.
