      abstract     = {This paper presents a comprehensive geoneutrino measurement
                      using the Borexino detector, located atLaboratori Nazionali
                      del Gran Sasso (LNGS) in Italy. 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

                      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

                      −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
