abstract

  • The central Andean Cordillera of Peru, Bolivia, northwestern Argentina, and northern Chile may be divided into three fundamental geologic provinces. These are the coastal volcanic arc; the Jurassic and Cretaceous miogeosynclinal sedimentary belt that dominates the geology of the high Andes of Peru; and the Eastern Cordillera of southeastern Peru, central Bolivia and northwestern Argentina. We present 45 new analyses of ore minerals from 31 mining districts and two of host rocks from province III and summarize our results together with other data available in the literature. Isotopic compositions of ore lead from the above provinces conform to neighboring but distinct fields on Pb isotope covariation diagrams. -from Authors
