Abstract
GPR models are instrumental in improving procedures of signal processing and developing indicators for GPR data interpretation. The paper presents GPR models of basic types of geostructural discontinuities in alluvial placers of Yakutia. Frozen rock massif of placer deposits is characterized by layered structure and includes discontinuities related to disturbance of rock, relict streams, and boulder inclusions where minerals are usually concentrated. It has been shown that geostructural discontinuities of diamond placer areas indicate an anomaly of waveform as chaotic distribution of GPR signals. Field data processing resulted in identification of the zone of bedrock discontinuity in the diamond deposit Mayat (Yakutia province in Siberia). Analysis of GPR data and geological sampling results allowed us to refine the outline of the placer rich in diamonds.
