Thermal History of the Moon

I HAVE already used 1 the creep behaviour of the mascons in my model of their origin and morphology 2 to set limits on the internal temperature of the Moon at present, former and primordial epochs. Results for the present are consistent with the upper limit obtained by Ness 3 from the electrical conductivity of the Moon implied by magnetometry in space. The purpose of this article is to use the approximation to the central temperature set by the result of Ness in order to correct previous solutions 4–7 of the heat-conduction equation, to infer possible thermal histories consistent with the present thermal regime.
