Olivine-hornblende-lamprophyre dikes from Quebrada los Sapos, El Teniente, Central Chile (34°S): implications for the temporal geochemical evolution of the Andean subarc mantle
Mafic Mg-olivine (Fo88)4-hornblende lamprophyre dikes, with Ni -190 ppm and Cr -390 ppm, cut late Miocene lavas in the Quebrada los Sapos a few kilometers west of the El Teniente Cu-Mo mine. These dikes have petro-chemical affinities with other less primitive, Pliocene (2.9-3.9 Ma), olivine-free lam...
