Anti-neutrinos ($\bar{\nu}_{e}$) emitted from radioactive isotopes inside the Earth, geo-neutrinos, bring unique and direct information about the Earth's interior and thermal dynamics. Geo-neutrino research has provided a new tool to study the Earth. In fact, existing neutrino experiments successfully estimate our planet's radiogenic heat production and are beginning to constrain composition models of the bulk silicate Earth. Understanding and identifying the Earth's energy budget is a fundamental question in geology. Quantitive information about the radiogenic heat production is essential for establishing the energy budget, which in turn is key to understanding the energy balance and thermal evolution of the Earth. The purpose of this workshop is to bring together geophysics, geochemistry and neutrino physics communities in order to share the latest achievements and future prospects this interdisciplinary research field.
