The analysis is the result of 3262.74 days of data betweenDecember 2007 and April 2019. The paper describes improved analysis techniques and optimized dataselection, which includes enlarged fiducial volume and sophisticated cosmogenic veto. The reported exposureof ð1.29 ` 0.05Þ × 1032 protons × year represents an increase by a factor of two over a previous Borexinoanalysis reported in 2015. By observing 52.6þ9.4ðstatÞþ2.7ðsysÞ geoneutrinos $(68\%$ interval) from 238U and −8.6 −2.1232Th, a geoneutrino signal of 47.0þ8.4ðstatÞþ2.4ðsysÞ TNU with $þ18.3\%$ total precision was obtained. This −7.7 −1.9 −17.2result assumes the same Th/U mass ratio as found in chondritic CI meteorites but compatible results were foundwhen contributions from 238U and 232Th were both fit as free parameters. Antineutrino background fromreactors is fit unconstrained and found compatible with the expectations. The null-hypothesis of observing ageoneutrino signal from the mantle is excluded at a $99.0\%$ C.L. when exploiting detailed knowledge of the localcrust near the experimental site. Measured mantle signal of 21.2þ9.5ðstatÞþ1.1ðsysÞ TNU corresponds to the −9.0 −0.9productionofaradiogenicheatof24.6þ11.1 $TW(68\%interval)from238Uand232Thinthemantle.Assuming$ $−10.418\%contributionof40Kinthemantleand8.1þ1.9$ TWoftotalradiogenicheatofthelithosphere,theBorexino −1.4estimate of the total radiogenic heat of the Earth is 38.2þ13.6 TW, which corresponds to the convective Urey −12.7ratio of 0.78þ0.41. These values are compatible with different geological predictions, however there is a ∼2.4σ −0.28tension with those Earth models which predict the lowest concentration of heat-producing elements in the mantle. In addition, by constraining the number of expected reactor antineutrino events, the existence of a hypothetical georeactor at the center of the Earth having power greater than 2.4 TW is excluded at $95\%$ C.L. Particular attention is given to the description of all analysis details which should be of interest for the next generation of geoneutrino measurements using liquid scintillator detectors.}, cin = {IKP-2}, ddc = {530}, cid = {I:(DE-Juel1)IKP-2-20111104}, pnm = {612 - Cosmic Matter in the Laboratory (POF3-612)}, pid = {G:(DE-HGF)POF3-612}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000508453600004}, doi = {10.1103/PhysRevD.101.012009}, url = {https://juser.fz-juelich.de/record/873209}, }
