Abstract Placer gold is rich in Mohe, Daxinganling region, Heilongjiang Province. It is an effective approach to search gold deposit using the information of gold placer, with the study on tectonic features, distribution and concentration of gold placer and regional denudation depth. Analysis on the tectonics and degree of denudation is the key step to locate the targets in placer gold enriched areas. The coefficient of dissolution can indicate the source of placer gold. Isotopes of Pb can reveal the parent rock for mineralization. The correlation study of ore, magmatic rocks, strata and Pb isotopes of basement has become an internationally recognized way to distinguish the origin of Pb isotopes. Using Pb isotopes to trace parent rocks has been successful in the assessment of ores. The characteristic values of Pb isotopes of the region resemble those of the source region. Thus the element can be employed as an indicator for gold deposit prospecting in placer gold enriched area.
