Their grain size composition is related to the peculiarities of rocks in the glacier bed. It is formed during the crushing, abrasion, and mixing of the glacier-rafted, assimilated, and transported material during its transportation and deposition, which determines variability of the grain size composition of moraines.

Placers related to the Precambrian sources are characterized by the presence of fine and thin gold (size 0.1‒0.25 mm) and, as a rule, are not of commercial interest. They make up alluvial bar and coastal-marine allochthonous placers. They are considered as complex (mainly rare metal–titanium) placers, where gold occurs as associated component). Placers related to sources of the Mesozoic ore formation stage are assigned to the class of small and medium reserves (gold size ranging from the dust-size to 0.2‒0.25 mm or more) and are usually mined by prospectors' teams. Placers on the platforms do not make up sheet deposits, since they are formed mainly due to sources that do not generate placers.

The Tetyugino lydites contain mainly biophile elements (P, Co, Cu, Mo, V, Ba), while the Shunga lydites are dominated by lithophile elements (Li, Rb, Cs). The trace element composition of lydites indicates that their formation took place on the periphery of the hydrothermal system, whereas the Tetyugino site was closer to the hydrothermal discharge zone than the Shunga site.
