Tungsten is one of the elements, in the search for which metallometric survey faces some difficulties. Thus, in the Eastern Transbaikalia on a number of ore occurrences represented by quartz-wolframite veins occurring among granitoids, no clear halos of tungsten dispersion were recorded with the usual survey methodology. Sometimes it is fixed in scattered samples, which does not allow with satisfactory accuracy to set mining excavations for opening of ore bodies. For development of the most rational methodology of selection and processing of metallometric samples it is necessary to know the distribution of the sought elements in loose sediments.
