| Lead Isotope Composition and Sources of Trace Lead in Placer Gold of the Hunchun River Valley |
| The isotope analysis of trace lead in placer gold has special meaning. From μ,υ and ω of the lead isotopes,the sources of the placer gold and the original deposit can be found. The lead isotope analysis of placer gold as well as rocks and minerals nearby in the Hunchun River Valley is very important in searching for gold deposits and collecting basic geological data in that area. The separation and enrichment of Pb are carried out by means of anion and cation exchange resin. In this way Pb can be separated from Au and its isotopes can be determined accurately. |
