Thermal History of the Earth with consideration of the Variable Thermal Conductivity of its Mantle

Abstract

Data about the abundance of the radioactive elements and the thermal conductivity of the Earth are in favour of the view that its initial temperature To(r) must have been below the melting temperature. The results of the calculations of To(Y) are presented for the Earth considered as being formed through accumulation of particles of a gas-dust protoplanetary cloud,
