Abstract : By studying the facies of seacoasts, it was determined that sedimentary rocks provide the main source. The litoral drift of sediments caused by waves represents the general dynamical condition. The waves separate the heavy minerals on beaches, but the conditions of separation often change. The study of recent deposits discloses that they consist, as a rule, of trangressive layers with buried relics of accumulative forms. The latter include fields of heavy minerals. (Author)
