### Description

The $\nu_{e}$ from radioactive decays (238U, 232Th, 40K) inside the Earth, called geoneutrinos provide the best way to investigate the composition of the Earth. First experimental results and evidence of these neutrinos were observed by KamLAND and Borexino utilising the inverse beta decay process. Using this process the directionality of the neutrino can not be measured making the measurements sensitive only to the bulk composition. In our study utilising the Likelihood ratio test, we investigate ̄$\bar{\nu} + e$ elastic scattering as a technique to measure the neutrino directionality and the geochemical structure of the Earth. Such a measurement could take place at the proposed ANDES laboratory to be completed in 2022 in Chile.
