Description

We consider a possibility to use solar neutrinos for studies of small scale structures of the Earth and for geological research. Effects of thin layers of matter with density contrast on oscillations of Beryllium neutrinos inside the Earth are studied. We find that change of the ⁷Be neutrino flux can reach 0.25% for layers with density of oil and size 10 - 100 km. Problems of detection are discussed. A hypothetical method would consist of measuring the ⁷Be - flux by, e.g., a large deep underwater detector - submarine which could change its location.
