内容記述 | On the assumption that hot magma intrudes suddenly in a spherical cavity in the earth's crust, the conduction of heat inside and outside the magma is discussed. The changes in the geothermal gradient and consequently the heat flow at the earth's surface right up the magma are then calculated. It is assumed 1) that the initial temperatures are constant and zero respectively inside and outside the sphere and 2) that the temperature at the earth's surface is always kept at zero. | |||||
