Аннотация: RussianSand-gravel mixtures (SGM) relate to multipurpose components using in many different industries. Traditionally different modifications of the resistivity method are applied for searching and exploration SGM deposits because it allows determining high-resistivity sand-gravel bodies against the background of more conductive enclosed rocks. For several years, authors carried out works as vertical electric soundings (VES) and electrical resistivity tomography (ERT) methods with measuring of induced polarization (IP) at various deposits of sand and gravel. Laboratory tests and measurement in-situ also were conducted. Authors suggest that one of the main cause of chargeability anomalies are electronically - conducting minerals present in the gravel of magmatic origin. Since the identification of areas with a high content of gravel and pebbles within the sand-gravel deposit is an important task for geophysics, we circumstantially study the IP field in sand gravel deposits and assess the efficiency of VES-IP complex for exploration of sand gravel deposits.
