Description
We provide the indication of high flux of $^{40}K$ geo-antineutrino and geo-neutrino ($^{40}K$-geo-($\bar{\nu}+\nu$)) with Borexino Phase III data. Simultaneously we obtained the count rates of events from $^{7}$Be, pep and CNO solar neutrinos. MC pseudo-experiments showed that the case of high metallicity Sun and absence of $^{40}K$-geo-($\bar{\nu}+\nu$) can not imitate the result of multivariate fit analysis of Borexino Phase III data with introducing $^{40}K$-geo-($\bar{\nu}+\nu$) events. We also provide arguments for the high abundance of potassium in the Earth. Large amounts of $^{40}K$ should produce a significant heat flow that should affect the Earth's internal processes. We present the results of modeling mantle convection taking into account excess heat from $^{40}K$.
