Abstract

The Mississippi Valley-type (MVT) Zn-Pb district of San Vicente is located in central Peru (300 km east of Lima) within the carbonate rocks of the Triassic-Jurassic Pucara basin. Detailed carbon and oxygen isotope studies of the carbonates and associated organic matter from the main deposit and minor ore-occurrences provide new insights on the mechanism of ore-precipitation in San Vicente. The regional homogeneity of the isotopic composition of the altered host and gangue carbonates, coupled with the strong mineralogical and petrographic similarities of the distinct MVT-occurrences reflects that the mineralizing processes were similar in the whole San Vicente belt, suggesting the existence of a regional mineralizing hydrothermal system with interconnected plumbing.
