Crustal contributions to arc magmatism in the Andes of Central Chile
Fifteen andesite-dacite stratovolcanoes on the volcanic front of a single segment of the Andean arc show along-arc changes in isotopic and elemental ratios that demonstrate large crustal contributions to magma genesis. All 15 centers lie 90 km above the Benioff zone and 280 _+ 20 km from the trench axis. Rate and geometry of subduction and composition and age of subducted sediments and seafloor...
متن کاملMineralogical, Geochemical and Isotopic Study of the Active Tailings Impoundment Carén from the Porphyry Copper Deposit El Teniente, Chile
At the active tailings impoundment Carén (surface 22 km) from the porphyry copper mine El Teniente, Chile, initial steps of primary mineral alteration and geochemical changes after deposition were studied. The tailings contained up to 3 vol% sulfides (mainly pyrite). At five points in the tailings impoundment, water samples up to a depth of 4 m were taken from piezometer. Preliminary data showe...
