Different contribution of mantle and ancient crustal sources is identified for each group. The Pb isotopic composition of galena of the Upper Karalon deposit indicates its genetic link with ore-hosting granites, the age of which (∼600 Ma) could be close to the age of the earliest stage of formation of gold–quartz mineralization.

Gold in the mantle: A global assessment of abundance
Gold has been one of the least studied elements in the mantle. There are several reasons for this, including the very low levels of Au in the mantle, making analysis difficult, and the mono-isotopic nature of Au, which makes isotope dilution, the technique commonly used to analyse the geochemically similar platinum group elements (PGE), impossible.
