FIELD: prospecting for gold-ore fields. SUBSTANCE: sampling of earth air is carried out in closed areas by certain system by pumping with vacuum pump and by simultaneous passing of samples through filter and sorbent with isolation of mobile form of direct elements-indicators. Filter- and sorbent-selected samples are analyzed by high-sensitivity method which does not require preparation of samples to determine content of direct elements-indicators, for example, gold, arsenic, antimony, wolfram. Anomalous sections corresponding to desired objects are isolated by quantitative relationships of these elements. EFFECT: improved authenticity of method. 4 cl
