Metalliferous paragenesis of the San José mine, Oruro, Bolivia
The San José silver-tin deposit, Oruro, is located in the Cordillera Oriental, which contains most of the metalliferous mineralizations of Bolivia and is related to a quartz-latite dome of Miocene age. The mineral paragenesis encountered in this study is composed of cassiterite, stannite, miargyrite...

| Sumario: | The San José silver-tin deposit, Oruro, is located in the Cordillera Oriental, which contains most of the metalliferous mineralizations of Bolivia and is related to a quartz-latite dome of Miocene age. The mineral paragenesis encountered in this study is composed of cassiterite, stannite, miargyrite, pyrargyrite, andorite and Bi-rich andorite, jamesonite, pavonite/benjaminite, boulangerite, owyheeite, ramdohrite and Bi-rich ramdohrite, bismuthinite, besides pyrite, chalcopyrite, Ag-rich tetrahedrite, galena and sphalerite, all of which are analyzed by electron microprobe analysis. With semi-quantitative SEM/EDS and XRD analyses, rhodostannite and kësterite/ferrokësterite were found in association with andorite, and chalcostibite was determined by XRD, in association with zinkenite, tetrahedrite and pyrite. © 2007 Elsevier Ltd.
