Abstract
New geochronological data of U-Pb, Re-Os and the lead isotope analysis of the Cu-Mo-Au mineral deposits are reported in the Trapiche and Constancia around Apurimac province, southeastern part of Peru. The measured ages were the first regional pulse of previously reported mineralization age between 28 and 33 Ma. The lead isotopic results indicate two sources of mineralization. The first source is thought to be derived from the upper crust and the second one is thought to be derived from a mixture of the upper crust and the lower crust.
