Geoneutrino and Hydridic Earth model. Version 2

TL;DR

This paper evaluates Earth's internal composition and heat production based on the Hydridic Earth model, suggesting Earth expansion and proposing a large-scale geoneutrino detector to distinguish between competing models.

Contribution

It introduces a revised version of the Hydridic Earth model with uniform K40 distribution and discusses the implications for Earth's heat and composition.

Findings

Calculated terrestrial heat production from U, Th, and K40 decays.

Proposed a large geoneutrino detector to differentiate Earth models.

Suggested Earth expansion to explain high heat production.

Abstract

Uranium, Thorium and Potassium-40 abundances in the Earth were calculated in the frame of Hydridic Earth model. Terrestrial heat producton from U, Th and K40 decays was calculated also. We must admit the existance of Earth expansion process to understand the obtained large value of terrestrial heat producton. The geoneutrino detector with volume more than 5 kT (LENA type) must be constructed to definitely separate between Bulk Silicat Earth model and Hydridic Earth model. In second version of the article we assume that K40 concentration distributes in the Earth uniformly.
