| Summary:

The review is conceived to help the reader to interpret present geoneutrino
results in the framework of Earth’s energetics and composition. Starting from
the comprehension of antineutrino production, propagation, and detection, the
status of the geoneutrino field is presented through the description of the
experimental and technological features of the Borexino and KamLAND ongoing
experiments. The current understanding of the energetical, geophysical and
geochemical traits of our planet is examined in a critical analysis of the
currently available models. By combining theoretical models and experimental
results, the mantle geoneutrino signal extracted from the results of the two
experiments demonstrates the effectiveness in investigating deep earth
radioactivity through geoneutrinos from different sites. The obtained results
are discussed and framed in the puzzle of the diverse classes of formulated
Bulk Silicate Earth models, analyzing their implications on planetary heat
budget and composition. As a final remark, we present the engaging
technological challenges and the future experiments envisaged for the next
decade in the geoneutrino field.
