In measuring geoneutrinos generated in the decay of natural radioactive elements in the earth\'s interior, liquid scintillator detectors appear to be able to accurately measure the radioactivity of uranium and thorium isotopes, the two main sources of terrestrial radiation. These detectors can serve as a unique and valuable tool for the study of geoneutrinos with wide-ranging implications for physical and geochemical models of the Earth. First global measurements by KamLAND detector led to the estimation of the radiogenic heat generation in the Earth. Placing detectors in different locations can be used to disentangle contributions of the crust, upper and lower mantle and core. I propose a network of detectors detecting both global Uranium and global Thorium in the vicinity of a specified location. This network would grossly reconstruct the tridimensional distribution of U and Th. Questions as long-term mantle evolution and circulation processes could be tackled, providing important insights in mantle non-uniformity and the Earth’s global dynamics. Other scientific questions, in neutrino physics and astrophysics, addressed by this network of detectors will be outlined.
