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.

페루 남동부 아뿌리막주 일대에 부존하는 트라피체 및 콘스탄시아 동-몰리브데늄-금광상의 새로운 U-Pb, Re-Os 지질연대 및 납동위원소 분석결과가 제시되었다. 금번 지질연대는 상기 지역에 대해 보고된 28~33 Ma 광화연령 구간의 첫 번째 광역적 펄스에 해당된다. 그리고 납동위원소 결과는 두 개의 광화작용 기원을 제시한다. 첫 번째는 상부지각에서 유래한 것이며 두 번째는 상부지각 및 하부지각의 혼합물로부터 기인한 것으로 사료된다.
