  The flux of geoneutrinos at any point on the Earth is a function of the
abundance and distribution of radioactive elements within our planet. This flux
has been successfully detected by the 1-kt KamLAND and 0.3-kt Borexino
detectors with these measurements being limited by their low statistics. The
planned 20-kt JUNO detector will provide an exciting opportunity to obtain a
high statistics measurement, which will provide data to address several
questions of geological importance. This paper presents the JUNO detector
design concept, the expected geo-neutrino signal and corresponding backgrounds.
The precision level of geo-neutrino measurements at JUNO is obtained with the
standard least-squares method. The potential of the Th/U ratio and mantle
measurements is also discussed.
