| Abstract: | The gold deposits in Chifeng-Chaoyang Area are located in the uplifted zones which are consisted of Archean metamorphic rocks and Hercynian-Yanshanian granites.The pyrites and galenas from the gold deposits in the area display a significant range of lead iso-tope compositions and fall on a linear array in the 207Pb/204Pb vs.206Pb/204Pb diagram.We considerthat the linear array may have ben produced by the mixing of lead from two different sources. One is Archean matamorphic rock and the other is upper mantle.The gold mineralization is closely related to the granites and diorites of the late Yanshan period about 100Ma. |
